arm: KVM: Allow an exit code to be tagged with a Virtual Abort

An asynchronous abort can also be triggered whilst running at EL2.
But instead of making that a new error code, we need to communicate
it to the rest of KVM together with the exit reason.
So let's hijack a single bit that allows the exception code to be
tagged with a "pending Abort" information.
