sgi-gru: misc GRU cleanup

Browse Source 
Misc trivial GRU drivers fixes:
	- fix long lines
	- eliminate extra whitespace
	- eliminate compiler warning
	- better validation of invalidate user parameters
	- bug fix for GRU TLB flush (not the cpu TLB flush)

These changes are all internal to the SGI GRU driver and have no effect
on the base kernel.
