Use resource_size function on resource object instead of explicit
computation.

Eliminate the following coccicheck warning:
./drivers/gpu/drm/amd/amdkfd/kfd_migrate.c:978:11-14: ERROR: Missing
resource_size with res

This patch was already applied in September: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0de5472a01804f43b7c8ddb1132bbfeb8b68674f

Which branch is this for?

Regards,
