gpu: nvgpu: Fix MISRA 21.2 violations [1/3]

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.

This change removes the usage of the '__a' argument scattered
throughout the nvgpu allocator code.
