David Teigland c78a87d0a1 dlm: fix plock use-after-free
Fix a regression from the original addition of nfs lock support
586759f03e.  When a synchronous
(non-nfs) plock completes, the waiting thread will wake up and
free the op struct.  This races with the user thread in
dev_write() which goes on to read the op's callback field to
check if the lock is async and needs a callback.  This check
can happen on the freed op.  The fix is to note the callback
value before the op can be freed.
