libpager: fix returning error on data_unlock
The _pager_lock_object call needs to be asynchronous because libpager is
single threaded, at least in the sense that individual memory objects
only process one request at a time. In this case, we're processing a
data_unlock request, and would have to handle a lock_completed message
before lock_object would return (synchronously).
* libpager/data-unlock.c (_pager_S_memory_object_data_unlock): Pass 0 to
sync parameter of _pager_lock_object() call.
