gpu: nvgpu: compact pte buffers
The lowest page table level may hold very few entries for mappings of
large pages, but a new page is allocated for each list of entries at the
lowest level, wasting memory and performance. Compact these so that the
new "allocation" of ptes is appended at the end of the previous
allocation, if there is space.
