smb: server: manage recv credits by counting posted recv_io and granted credits

(At least for me) the logic maintaining the count of posted
recv_io messages and the count of granted credits is much
easier to understand.

From there we can easily calculate the number of new_credits we'll
grant to the peer in outgoing send_io messages.

This will simplify the move to common logic that can be
shared between client and server in the following patches.
