LU-10212 ldlm: fix prolong for destroyed lock

For a IO request ofd_prolong_extent_locks use
a fast path if the lock is found by handle. If the lock
has LDLM_FL_DESTROYED, prolong should try a general path.

No lock was accounted for IO request with destroyed lock
and ESTALE error happaned for a client.
