95b9d5f9dd fix(virtio): monitor the waker with IORING_OP_POLL_ADD 
With `IORING_POLL_ADD_MULTI`, we do not need to re-add the waker
to the ring.

Commit 0c4fc4e3ba also used IORING_OP_POLL_ADD for ioeventfds, which
was problematic because POLL_ADD does not clear the internal counter
of an eventfd when it creates a cqe. So once an ioeventfd is re-added
to the ring, it immediately generates a new cqe, despite that there is
no new MMIO yet. This causes the event loop thread to spin.

8291ce5f90 fix(kvm): calculate correct mask for 64bit MMIO 
1u64.wrapping_shl(64) returns 1 instead of 0. Without the fix, for 64bit
MMIO, the mask is 0 instead of u64::MAX.
