GFS2: Clean up of gdlm_lock function

The DLM never returns -EAGAIN in response to dlm_lock(), and even
if it did, the test in gdlm_lock() was wrong anyway. Once that
test is removed, it is possible to greatly simplify this code
by simply using a "normal" error return code (0 for success).

We then no longer need the LM_OUT_ASYNC return code which can
be removed.
