  SVN rev 203094 on 2010-01-27 20:30:14Z by marius
  
  - 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.
