x86,arm: Change arch_livepatch_quiesce() declaration.

On ARM we need an alternative VA region to poke in the
hypervisor .text data. And since this is setup during runtime
we may fail (it uses vmap so most likely error is ENOMEM).

As such this error needs to be bubbled up and also abort
the livepatching if it occurs.
