Scott Long d995644382 gpu: nvgpu: fix MISRA Rule 11.6 issue with fence pool mgmt ...

MISRA Rule 11.6 prohibits the casting of an integer value to a
void *.

The nvgpu allocator used for the fence pool stores the base
address of the associated memory as a u64 and returns it via
nvgpu_alloc_base().

In gk20a_free_fence_pool() this u64 value was cast to a void *
before being passed to nvgpu_vfree() (leading to the violation).

This change modifies gk20a_free_fence_pool() to cast the base
address back to the original struct gk20a_fence * to eliminate
the violation.
