6.6-stable review patch. If anyone has any objections, please let me know.

commit 79280191c2fd7f24899bbd640003b5389d3c109c upstream.
cifs_pick_channel iterates candidate channels using cur. The reconnect-state test mistakenly used a different variable.
This checked the wrong slot and would cause us to skip a healthy channel and to dispatch on one that needs reconnect, occasionally failing operations when a channel was down.
Fix by replacing for the correct variable.
