x86/alternatives: Move apply_relocation() out of init section

This function is now called from a few places that are no __init_or_module,
resulting a link time warning:

  WARNING: modpost: vmlinux: section mismatch in reference: patch_dest+0x8a (section: .text) -> apply_relocation (section: .init.text)

Remove the annotation here.

[ mingo: Also sync up add_nop() with these changes. ]

Fixes: 17bce3b2ae2d ("x86/callthunks: Handle %rip-relative relocations in call thunk template")
