LU-13227 ofd: update lvb before dropping server lock

If this is a local lock on a server namespace and this was
the last reference, lock will be canceled directly instead
of staying at LRU, this might be problem that we will lose
O_DIRECT write size expanding without LVB updating.

This patch try to fix the problem by updating LVB just after
writing but before lock is dropped.
