ocfs2/dlm: Wait on lockres instead of erroring cancel requests
In case a downconvert is queued, and a flock receives a signal,
BUG_ON(lockres->l_action != OCFS2_AST_INVALID) is triggered
because a lock cancel triggers a dlmunlock while an AST is
scheduled.
To avoid this, allow a LKM_CANCEL to pass through, and let it
wait on __dlm_wait_on_lockres().
