6cca2ea9be btrfs-progs: more sanity checks in read_tree_block_fs_info 
If blocksize is 0, it passes the IS_ALIGNED check but fails later as the
length of ebs will be zero.

7c646c538e btrfs-progs: qgroup: Fix regression leads to corrupted qgroup status 
Commit 93dabf211d
Author: Mark Fasheh <mfasheh@suse.de>
Date:   Fri Jun 17 13:37:48 2016 -0700

    btrfs-progs: check: verify qgroups above level 0

This commit introduced a new regression which corrupts
read_qgroup_status, since it iterate leaf with manually specified slot,
not correct path->slot[0].

This leads to wrong slot[0] and read_qgroup_status() will read out wrong
flags, leading to regression.

Fix read_qgroup_status() by using eb and slot instread of wrong path
strucutre.

3296d058b7 btrfs-progs: super-recover: Reuse btrfs_read_dev_super function 
We have enhanced super block validation check in disk_io.c, while
super-recover doesn't use that function and use a custom one.

That is duplicated, so reuse btrfs_read_dev_super to handle it, which
not only enhanced super check, but also reduce the code length.

50c8c995ea btrfs-progs: Return more meaningful value for btrfs_read_deve_super 
btrfs_read_dev_super() only returns 0 or -1, which doesn't really help,
caller won't know if it's caused by bad superblock or superblock out of
range.

Return -errno if pread64() return -1, and return -EOF if none or part of
the super is read out, and return what check_super() returned.

So caller can get -EIO to catch real corrupted super blocks.
