gpu: nvgpu: unit: initialize nvgpu_mem variables

Browse Source 
There were several places were nvgpu_mem structs were declared on the
stack and not initialized. Some fields could be used erroneously by
underlying APIs.

To allow the initialization of an array of nvgpu_mem in
test_dma_alloc_fi_delayed_enable(), the array length had to be changed
from a const to a macro.
