ldlm_glimpse_ast() is registered for server lock which means
when client send a glimpse request, it just return a special error
for this lock, it is possible that local object has size expanding
with this PW lock, so we should try update LVB upon error.

Originally, ldlm_cb_interpret() has codes to handle this error,
but it only try to handle case with some clients race, it doesn't
cover server lock cases especially after we turn on lockless for DIO.

Fixes: 6bce5367

 ("LU-4198 clio: turn on lockless for some kind of IO")
