cifs: reconnect helper should set reconnect for the right channel
commitc3326a61cd
upstream. We introduced a helper function to be used by non-cifsd threads to mark the connection for reconnect. For multichannel, when only a particular channel needs to be reconnected, this had a bug. This change fixes that by marking that particular channel for reconnect. Fixes:dca65818c8
