intel_iommu: Allow both Status Write and Interrupt Flag in QI wait
FreeBSD does both, and this appears to be perfectly valid. The VT-d
spec even talks about the ordering (the status write should be done
first, unsurprisingly).
We certainly shouldn't assert() and abort QEMU if the guest asks for
both.
Fixes: ed7b8fbcfb88 ("intel-iommu: add supports for queued invalidation interface")
Closes: https://gitlab.com/qemu-project/qemu/-/issues/3028
