Fixup channel submit IOCTL syncpoint parameters (#2774)

Browse source 
* Fixup channel submit IOCTL syncpoint parameters

The current arguments worked by happenstance as games only ever submit
one syncpoint and request one fence back, if a game were to do something
other than this then the arguments would've been parsed entirely wrong.

* Address feedback
