[SMSS] Fix three SmpLoadSubSystem bugs related to the SB_CREATE_SESSION callback. 
This fixes starting the Windows 2000 POSIX subsystem in ReactOS.

- The CreateSession pointer was initialized against the SbApiMsg variable, but
  it was the other SbApiMsg2 that was being initialized and sent through LPC.

- Do not overwrite the MuSessionId (Terminal Services session ID) variable with
  the generated environment subsystem session ID from SmpAllocateSessionId().

- Actually initialize the SbApiMsg ApiNumber for the CreateSession LPC call.

All those bugs could have been avoided *IF*, rather than (badly) duplicating
its code, the existing SmpSbCreateSession() function had been used instead.

- "Not sure these field mean what I think they do -- but clear them" ... ◔_◔
  Those fields are related to the debug client interface (DbgUi) and session
  in case the subsystem being started is going to be debugged. These have
  nothing to do with the MuSessionId. Clarify this in the SB_CREATE_SESSION_MSG
  structure and in the SmpSbCreateSession() function.
