cifs: cifs_pick_channel should try selecting active channels
cifs_pick_channel today just selects a channel based on the policy of least loaded channel. However, it does not take into account if the channel needs reconnect. As a result, we can have failures in send that can be completely avoided. This change doesn't make a channel a candidate for this selection if it needs reconnect.
