video: tegra: nvmap: Fix overflow in nvmap_heap
do_heap_alloc locates a suitable free block from a nvmap heap given a size and alignment. Unfortunately, if a heap block happens to be smaller than the alignment passed to the function, an integer overflow will occur, and a block that's too small gets accidentally returned.
