Subject: cifs: reconnect helper should set reconnect for the right channel
From: Shyam Prasad N <sprasad@xxxxxxxxxxxxx>
commit c3326a61cdbf3ce1273d9198b6cbf90965d7e029 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: dca65818c80c ("cifs: use a different reconnect helper for non-cifsd threads")
