Akihiko Odaki 15377f6e79 msix: Assert that specified vector is in range
There were several different ways to deal with the situation where the
vector specified for a msix function is out of bound:
- early return a function and keep progresssing
- propagate the error to the caller
- mark msix unusable
- assert it is in bound
- just ignore

An out-of-bound vector should not be specified if the device
implementation is correct so let msix functions always assert that the
specified vector is in range.

An exceptional case is virtio-pci, which allows the guest to configure
vectors. For virtio-pci, it is more appropriate to introduce its own
checks because it is sometimes too late to check the vector range in
msix functions.
