Previously we would only loop over the iface list once.
This patch tries to loop over multiple times until all channels are
opened. It will also try to reuse RSS ifaces.

This wouldn't build due to CONFIG_CIFS_STATS2 but I merged it and
fixed the build break by adding a followon patch which enables in_send
and num_waiters by default (not requiring CONFIG_CIFS_STATS2 for those
two counters)
