gpu: nvgpu: Fix MISRA 21.2 violations (nvgpu_mem.c, mm.c)

Browse Source 
MISRA 21.2 states that we may not use reserved identifiers; since
all identifiers beginning with '_' are reserved by libc, the usage
of '__' as a prefix is disallowed.

Handle the 21.2 fixes for nvgpu_mem.c and mm.c; this deletes the
'__' prefixes and slightly renames the __nvgpu_aperture_mask()
function since there's a coherent version and a general version.
