habanalabs: use u64 when comparing variables' sum to u32_max
This patch fixes two smatch warnings about two if statements that are always true because of the types of the variables used - u32 when comparing the sum to u32_max. The patch changes the types to be u64 so the accumalted sum can be checked if it is larger than u32_max Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
