PV-on-HVM: Add new ioreq 'invalidate' for zapping ioemu-dm mapccahe
after balloon operations in an HVM guest.
This removes the I/O port hack from the guest OS, and from ioemu.
Also we flush on reservation *increases* as well as decreases. This is
necessary until qemu-dm can demand-fault page mappings into existing
valid buckets.
