This is a partial revert of commit d7f0b70d30ffb9bbe6b8a3e1035cf0b79965ef53
("UBIFS: Add security.* XATTR support for the UBIFS").
As UBIFS does not use generic inode xattr inode operations
the code behind sb->s_xattr is never called.
Remove that dead code for now.

After the merge window (and my vacation) I'll have the time to
re-introduce/work security xattr support.
Thanks,
