habanalabs: fix MMU number of pages calculation
The requested allocation size is 64bit, hence the number of requested pages and the total requested size should 64bit as well. This patch fixes all places where these are treated as 32bit. Signed-off-by: Omer Shpigelman <oshpigelman@habana.ai> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>
