gpu: nvgpu: Fix MISRA 21.2 violations (pd_cache.c)

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.

Fixes for all the pd_cache functions that use '__' prefixes. This
was trivial: the '__' prefix was simply deleted.
