smb: client: let recv_done() queue a refill when the peer is low on credits

commit defb3c05fee94b296eebe05aaea16d2664b00252 upstream.

In captures I saw that Windows was granting 191 credits in a batch
when its peer posted a lot of messages. We are asking for a
credit target of 255 and 191 is 252*3/4.

So we also use that logic in order to fill the
recv buffers available to the peer.
