While running alsa_conformance_test against the virtio-snd device, the
driver will randomly stop getting irq events forever. (vp_interrupt will
never get called).
At the same time, the host device will still see an uncleared
`interrupt_status` so the `trigger_interrupt` -> `signal`
will just drop the interrupt signal on
the host device side. And the device can't be used forever when the
issue happens.
Root cause:
Irq resample events never get handled in the virtio-snd device, so the
interrupt handler in guest just can't get notified if there are some
unhanded interrupts in the irq line during the resample event.
Changes:
- Add `f_resample` future in the run_worker
- Use `select!` from futures crate with `async-await` feature
- Change local interrupt in run_worker to Rc<RefCell<interrupt>>
- Use anyhow::Context for errors

Add interrupt redirection entries to MADT so that the legacy pin-based
interrupts are correctly reported as level triggered. This matches the
entries in the existing MPTable, but those are not availble when booting
with OVMF, which only provides ACPI tables.
This fixes an issue where USB device sharing was failing in some cases
when booted with ACPI only, since our xhci controller emulation only
supports pin-based interrupts (not MSI-X) and would not work correctly
when the guest incorrectly treated its IRQ as edge triggered.

Pci spec defines Interrupt Pin register that devices don't use an interrupt pin
must put a 0 in this register. The values 05h throgh FFh are reserved. So if
vfio-pci reads interrupt pin register and gets value like 0, 0x5~0xFF, it means
vfio pci device doesn't support legacy intx, then interrupt_evt and
interrupt_resample_evt don't need to be saved, finnaly enable_intx ioctl won't
be called into kernel vfio.
This fixes an error message during CrOS reboot, poweroff, xhci controller's
suspend and resume on Brya ManaTEE:
ERROR: vfio 0000:00:0d.0 device Intx enable failed: failed to enable vfio device's
irq: Invalid argument (os error 22).
BUG=None
TEST=check vfio-pci xhci controller (00:0d.0)'s function during suspend and resume.

This change separates the number of queues of the proxy device from the
number of queues of the actual VVU device. It also fixes the device type
constant to the number specified by the spec. Also, change PciClassCode
for legacy devices. The guest VFIO driver code doesn't enumerate the
proxy device without it.
