Sachit Kadle 0a1e7c6b09 gpu: nvgpu: correct gpfifo size calculation ...

This change fixes up the calculation of gpfifo entries, to be
allocated depending on the ioctl used:

1) For the legacy ALLOC_GPFIFO ioctl, we preserve the calculation
of gpfifo entries within the kernel.

2) For the new ALLOC_GPFIFO_EX ioctl, we assume that userspace has
pre-calculated power-of-2 value. We process this value un-modified
and only verify that it is a valid power-of-2.
