x86, asm: Cleanup unnecssary macros in asm-offsets.c
PAGE_SIZE_asm, PAGE_SHIFT_asm, THREAD_SIZE_asm can be safely removed from asm-offsets.c, and be replaced by their non-'_asm' counterparts in the code that uses them, since the _AC macro defined in include/linux/const.h makes PAGE_SIZE/PAGE_SHIFT/THREAD_SIZE work with as.
