cifs: fix potential race with cifsd thread
To avoid racing with demultiplex thread while it is handling data on
socket, use cifs_signal_cifsd_for_reconnect() helper for marking
current server to reconnect and let the demultiplex thread handle the
rest.
Fixes: dca65818c80c ("cifs: use a different reconnect helper for non-cifsd threads")
