We have been setting it to the old head value. This is usually
harmless since the new head will virtually always be ahead of the
old head for claim_log_and_clear_rollback_info, but can cause trouble
in some edge cases.

Following sequence of events can happen.
- Client releases an inode, queues cap release message.
- A 'lookup' reply brings the same inode back, but the reply
doesn't contain xattrs because MDS didn't receive the cap release
message and thought client already has up-to-data xattrs.
The fix is force sending a getattr request to MDS if xattrs_version is 0.
The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client does
not have xattr.

Fixes two things:
* EC pools are now permissible if they have a cache overlay
* Pools are not permissible if they are a cache tier.

The implicit creation of a ruleset when creating a pool is convenient
when nothing is specified. However, if the caller sets a ruleset name,
it should not implicitly create it but return ENOENT instead. Silently
creating a ruleset when there is a typo in the ruleset name is
confusing.

Otherwise the FDCache will keep a file descriptor to a file that was
removed from the file system. This may create various type of errors
because the OSD checking the FDCache will assume the file that contains
information for an object exists although it does not. For instance in
the following:
* rados put object file
* rm file from the primary
* repair the pg to which the object is mapped
if the FDCache is not cleared, repair will incorrectly pull a copy from
a replica and write it to the now unlinked file. Later on, it will
assume the file exists on the primary and only be partially correct :
the data can still be accessed via the file descriptor but any operation
using the path name will fail.

set new inode's xattr version to 1 even if it has no xattr. This allow
client to differentiate no xattr in inode from MDS skips sending xattr
to client (because MDS think client already has uptodate xattr).

This is mostly relevant in testing clusters, but it ensures that an OSD
disconnecting from the monitor at the wrong time will still see any recent
map updates and prevent accidental loss of map injection into the OSD cluster.

Cancel the command op timeout event before we clear out the op from the
session struct. This isn't strictly necessary because command_op_cancel
will "gracefully" handle the case where the tid is no longer present, but
this avoids that noise and is cleaner.

The C_CancelOp path assumes op->session != NULL. Cancel that op before
we clear it. This fixes a crash like
