Subject: [PATCH] ext3: journal all modifications in ext3_xattr_set_handle

ext3_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.

Although ext3 doesn't have the crc issue, modifications
out of journal control are a Bad Thing.
