Now that we aren't abusing the kmap address space, there's no need for
this lock or to impose a limit on the rsize.

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.

This is help us to extend the code for future protocols that can use
another fid mechanism (as SMB2 that has it divided into two parts:
persistent and violatile).
Also rename variables and refactor the code around the changes.

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

Split all requests to echos, oplocks and others - each group uses
its own credit slot. This is indicated by new flags
CIFS_ECHO_OP and CIFS_OBREAK_OP
that are not used now for CIFS. This change is required to support
SMB2 protocol because of different processing of these commands.

For SMB2, this should be a no-op. Obviously if we wanted to do something
for the SMB2 case, we could also define an operation here for it.

We need a way to dispatch different operations for different versions.
Behold the smb_version_operations/values structures. For now, those
structures just hold the version enum value and nothing uses them.
Eventually, we'll expand them to cover other operations/values as we
change the callers to dispatch from here.
