Joseph Qi 151ec39119 Revert "fs: ocfs2: fix possible null-pointer dereferences in ocfs2_xa_prepare_entry()" 
commit 94b07b6f9e2e996afff7395de6b35f34f4cb10bf upstream.

This reverts commit 56e94ea132bb5c2c1d0b60a6aeb34dcb7d71a53d.

Commit 56e94ea132bb ("fs: ocfs2: fix possible null-pointer dereferences
in ocfs2_xa_prepare_entry()") introduces a regression that fail to
create directory with mount option user_xattr and acl.  Actually the
reported NULL pointer dereference case can be correctly handled by
loc->xl_ops->xlo_add_entry(), so revert it.
