I reproduced this running xfs/033 directly on a 4.3.0-rc2+ kernel
(linux-xfs tree) and xfsprogs-3.2.2 from fedora. The problem here is
that the mount complains about an invalid metadata LSN. Via dmesg:

...
XFS (dm-3): Mounting V5 Filesystem
XFS (dm-3): Corruption warning: Metadata has LSN (1:16) ahead of current LSN (1:2). Please unmount and run xfs_repair (>= v4.3) to resolve.
XFS (dm-3): log mount/recovery failed: error -22
XFS (dm-3): log mount failed
...

This occurs because older versions of xfs_repair unconditionally zero
out the log, which can lead to corruption after a crash on v5 superblock
(-m crc=1) filesystems. Therefore, the invalid log state is detected in
the kernel as of the commit referenced above and ultimately fixed in
xfsprogs v4.3. In other words, XFS on a v4.4 kernel requires xfsprogs
v4.3 or newer.

I'm not sure what the xfsprogs release status is (tot looks like it's at
4.3.0-rc2), but the fix is ultimately to upgrade to a supported
userspace.
