Turn these into asserts. The only two callers are create_object_context()
and get_object_context(), and they only get called when the object is no
longer missing.

Bug #3142 appears to be caused by the following sequence:
- object X missing on primary and replica
- [assert-ver,watch], notify, unwatch requests come in, get deferred
- object is recovered on primary, !missing, create_object_context
- populate_obc_watchers() does nothing, since still degraded
- notify happens now (odd but ok?)
- replica recovered, !degraded
- watch skips bc of bad assert
- unwatch trips up on an assert because populate_obc_watchers never
ran
Fix this by populating the obc watcher when !missing, not when
!degraded. This conditional dates back to Sam's original watch/notify
cleanup in October 2011.

This makes coverity happier because we check_op_pool_dne() may free
the Op (or Lingerop) structure(s), but the callers in the submit_*
paths dereference after calling. This is actually safe because they
never free new ops, but is confusing. Explicitly push this into a
separate helper.

If we don't have the inode, release the caps. There is no point in adding
it to our cache, and that is problematic anyway because it ends up with a
ref count of zero and no dentry that will get trimmed by trim_cache(),
leaving it stuck there on shutdown.
This also aligns us with the kernel client behavior.

Posix allows creating/opening a file with
open() with a mode that doesn't allow write (or read)

This means that correct permissions checking against
