How is this a bug? deliver_ee() is called every time we return from an exception, including when resuming into the hypervisor from a nested interrupt.

in exceptions.S: fast_resume, you have a check for HV and branch over the call to deliver_ee.

Hmm, I didn't remember that. :) In that case, I'm not sure the BUG_ON is necessary... but we can remove it the next time we're in there.
