reiserfs: fix inode mutex - reiserfs lock misordering
reiserfs_unpack() locks the inode mutex with reiserfs_mutex_lock_safe()
to protect against reiserfs lock dependency. However this protection
requires to have the reiserfs lock to be locked.
This is the case if reiserfs_unpack() is called by reiserfs_ioctl but
not from reiserfs_quota_on() when it tries to unpack tails of quota
files.
Fix the ordering of the two locks in reiserfs_unpack() to fix this
issue.
