gpu: nvgpu: Fix length passed to VIDMEM map
The call to __set_pd_level() for vidmem allocs had the wrong
length being passed in. This was a silent error since the subsequent
__set_pd_level() calls overwrote the bad mappings. However this
caused significantly more PDE/PTE writes than necessary since
each chunk could be mapped N times where N is the number of chunks
in an SGL.
