x86: Eliminate result signage problem in asm-x86_64/bitops.h
The return type of __scanbit() doesn't match the return type of find_{first,next}_bit(). Thus when you construct something like this: boolean ? __scanbit() : find_first_bit() you get an unsigned long result if "boolean" is true, and a signed long result if "boolean" is false.
