[PATCH 1/2 V2] ext4: journal all modifications in ext4_xattr_set_handle

[Eric Sandeen <sandeen@redhat.com>]

ext4_xattr_set_handle() was zeroing out an inode outside
of journaling constraints; this is one of the accesses that
was causing the crc errors in journal replay as seen in
kernel.org bugzilla #14354.
