cifs: handle cases where a channel is closed
[ Upstream commit 0c51cc6f2cb0108e7d49805f6e089cd85caab279 ]
So far, SMB multichannel could only scale up, but not
scale down the number of channels. In this series of
patch, we now allow the client to deal with the case
of multichannel disabled on the server when the share
is mounted. With that change, we now need the ability
to scale down the channels.
This change allows the client to deal with cases of
missing channels more gracefully.
