The syncpoint maximum value represents the maximum possible syncpt value at a given time, however due to PBs being submitted before max was incremented, for a brief moment of time this is not the case which could lead to invalid behaviour if a game waits on the fence at that specific time.
* 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
I happened to notice this when checking Ryu's IPC structures. After double checking with RE it seems the current check is incorrect so use the correct member to fix that.
