Ilya Maximets ef862b9e8e migration: Stop postcopy fault thread before notifying ...

POSTCOPY_NOTIFY_INBOUND_END handlers will remove userfault fds
from the postcopy_remote_fds array which could be still in
use by the fault thread. Let's stop the thread before
notification to avoid possible accessing wrong memory.
