gpu: nvgpu: Simplify compbits alloc and add needs_clear
Simplify compbits alloc by making the alloc function re-callable for
the buffer, and making it return the comptags info. This simplifies
the calling code: alloc_or_get vs. get + alloc + get again.
Add tracking whether the allocated compbits need clearing before they
can be used in PTEs. We do this, since clearing is part of the gmmu
map call on vgpu, which can fail.
