I decided to entirely move away from domain_crash_synchronous() in hypercall
context. So the code in domain_crash_synchronous() is just a warning for
errant code -- later it can become BUG_ON(). This means that multicall state
can remain per-cpu, unless per-vcpu seems much better (personally I think it
doesn't really matter either way so we may as well stick with what we have).
