X86: Wrap a helper for an assert in #ifndef NDEBUG

This function is used in exactly one place, and only in asserts
builds. Move it a few lines up before the use and only define it when
asserts are enabled. Fixes the release build under -Werror.

Also remove the forward declaration and commentary that was basically
identical to the code itself.
