Now that we're not kmapping so much at once, there's no need to cap
the wsize at the amount that can be simultaneously kmapped.

Since both CIFS and SMB2 use ses->capabilities (server->capabilities)
field but flags are different we should make such checks protocol
independent.

Since there are only 19 command codes, it also is easier to track by exact
command code than it was for cifs.

For SMB2 protocol we can add more than one credit for one received

Also we divide all requests by type: echoes, oplocks and others.
Each type uses its own slot pull.
