Let's use (short) and (unsigned short), which is more sensible, and more consistent with the other MAX/MIN defines. As you see in include/uapi/asm-generic/int-ll64.h, s16/u16 are typedef'ed as signed/unsigned short. So, this commit does not have a functional change. Remove the unneeded parentheses around ~0U while we are here.
