MFC: r203094
- Zero the MSI/MSI-X queue argument, otherwise mtx_init(9) can panic
indicating an already initialized lock.
- Check for an empty MSI/MSI-X queue entry before asserting that we have
received a MSI/MSI-X message in order to not panic in case of stray MSI/
MSI-X queue interrupts which may happen in case of using an interrupt
handler rather than a filter.
