ocfs2: fix race between crashed dio and rm
There is a race case between crashed dio and rm, which will lead to
OCFS2_VALID_FL not set read-only.
N1 N2
------------------------------------------------------------------------
dd with direct flag
rm file
crashed with an dio entry left
in orphan dir
clear OCFS2_VALID_FL in
ocfs2_remove_inode
recover N1 and read the corrupted inode,
and set filesystem read-only
So we skip the inode deletion this time and wait for dio entry recovered
first.
