smb: client: fix cifs_pick_channel when channels are equally loaded

Browse source

commit 663c28469d upstream.

cifs_pick_channel uses (start % chan_count) when channels are equally
loaded, but that can return a channel that failed the eligibility
checks.

Drop the fallback and return the scan-selected channel instead. If none
is eligible, keep the existing behavior of using the primary channel.
