Shyam Prasad N 94d0e33c5f cifs: refcount only the selected iface during interface update 
commit 7246210ecdd0cda97fa3e3bb15c32c6c2d9a23b5 upstream.

When the server interface for a channel is not active anymore,
we have the logic to select an alternative interface. However
this was not breaking out of the loop as soon as a new alternative
was found. As a result, some interfaces may get refcounted unintentionally.

There was also a bug in checking if we found an alternate iface.
Fixed that too.

Fixes: b54034a73baf ("cifs: during reconnect, update interface if necessary")
