Alex Waterman 4a3f84d257 gpu: nvgpu: Fix overflow of alloc length ...

Fix an issue where large ( > 4GB) allocations were not being computed
correctly. The two fields, pages and page_size, were both 32 bits so
when multiplied they easily overflowed. Simple fix is to cast them to
64 bits before multiplying them.
