[patch 2/2] move init_ext4_proc() last and add cleanup call exit_ext4_proc()

[markn@au1.ibm.com]

[-- Attachment #1: ext4-move-init_ext4_proc-add-cleanup.patch --]
[-- Type: text/plain, Size: 1052 bytes --]

The first problem that is addressed is that the addition of init_ext4_proc()
means that the code doesn't clean up after itself on a failure of
init_ext4_xattr(), and the second is that usually init_*_proc() should be
the last thing called, so we move it to the end and add the cleanup call to
exit_ext4_proc().
