gpu: nvgpu: Use correct PD for determining next aperture
When generating the aperture field for the PDE being programmed
we must use the next PD not the current PD. This is important for
cases on the dGPU where VIDMEM runs out.
In such cases the page table may reside in both VIDMEM and SYSMEM.
Thus, if a PDE points to a PDE in a different type of memory
(VIDMEM -> SYSMEM or SYSMEM -> VIDMEM) then the aperture will not
be programmed correctly if the code uses the current PD for
picking the next PD aperture.
