Fix that the INIT signal remains pending even after delivery of VM-exit/#VMEXIT(INIT) (#16) 
* Clear pending INIT signal

When the INIT signal is translated into corresponding VM-exit/#VMEXIT,
the signal should no longer be marked as pending. Otherwise, the signal
would be (incorrectly) delivered again.

Fix that the blocking by SMI bit maybe set when a VM-exit ends outside SMM (#15) 
* Fix that the blocking by SMI bit is set

The blocking by SMI bit of the guest interruptibility state VMCS should
not be set unless the VM-exit ends in SMM. This only happens under the
dual-monitor treatment, which is not implemented in Bochs.

b8f38eb8d3 Fix two bugs around monitor/mwait 
MONITOR relies on tickle_read_virtual to set the physical address, but it was
only doing so on TLB miss. So a MONITOR with a TLB hit would arm the most
recently accessed address instead of the requested one.

TLB invalidations disarmed the monitoring range, but didn't wake a CPU that
had already MWAIT-ed. Any instruction that invalidated TLB entries on other
CPUs could have caused an MWAIT-ing CPU to never wake.
