arm64: jump_label: mark arguments as const to satisfy asm constraints

Browse source

Inspired by x86 commit 864b435514b2("x86/jump_label: Mark arguments as
const to satisfy asm constraints"), mark arch_static_branch()'s and
arch_static_branch_jump()'s arguments as const to satisfy asm
constraints. And Steven in [1] also pointed out that "The "i"
constraint needs to be a constant."

Tested with building a simple external kernel module with "O0".
