Change the GRU instructions that manage contexts from inline functions to
out-of-line functions. This simplifies adding statistics & error checking
to these functions.

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.
