x86/mm: Regularize set_memory_p() parameters and make non-static
set_memory_p() is currently static. It has parameters that don't match set_memory_p() under arch/powerpc and that aren't congruent with the other set_memory_* functions. There's no good reason for the difference. Fix this by making the parameters consistent, and update the one existing call site. Make the function non-static and add it to include/asm/set_memory.h so that it is completely parallel to set_memory_np() and is usable in other modules. No functional change.
