arm64: add alt_cb_patch_nops prototype
alt_cb_patch_nops() is called through an inline asm macro, so
it does not need a prototype for the caller, but adding it
avoids this W=1 build warning:
arch/arm64/kernel/alternative.c:295:14: error: no previous prototype for 'alt_cb_patch_nops' [-Werror=missing-prototypes]
