Fix sending/receiving surface bits command.

Browse Source 
* Pass on proper command type to application
* On send let the server implementation decide to send
   2.2.9.2.1 Set Surface Bits Command (TS_SURFCMD_SET_SURF_BITS) or
   2.2.9.2.2 Stream Surface Bits Command (TS_SURFCMD_STREAM_SURF_BITS)
Thanks to @viniciusjarina for tracing the issue down.
