fix shifts possibly larger than type in major() macro

in theory this should not be an issue, since major() should only be applied to type dev_t, which is 64-bit. however, it appears some applications are not using dev_t but a smaller integer type (which works on Linux because the kernel's dev_t is really only 32-bit). to avoid the undefined behavior, do it as two shifts.
