Revert "x86/alternative: Make custom return thunk unconditional"
This reverts commit 53ebbe1c8c02aa7b7f072dd2f96bca4faa1daa59.
Revert the backport of upstream commit:
095b8303f383 ("x86/alternative: Make custom return thunk unconditional")
in order to backport the full version now that
770ae1b70952 ("x86/returnthunk: Allow different return thunks")
has been backported.
Revert it here so that the build breakage is kept at minimum.
