Peter Grehan 310dacd09b Various VirtIO improvements
PCI:
        - Properly handle interrupt fallback from MSIX to MSI to legacy.
          The host may not have sufficient resources to support MSIX,
          so we must be able to fallback to legacy interrupts.
        - Add interface to get the (sub) vendor and device IDs.
        - Rename flags to VTPCI_FLAG_* like other VirtIO drivers.
      Block:
        - No longer allocate vtblk_requests from separate UMA zone.
          malloc(9) from M_DEVBUF is sufficient. Assert segment counts
          at allocation.
        - More verbose error and debug messages.
      Network:
        - Remove stray write once variable.
      Virtqueue:
        - Shuffle code around in preparation of converting the mb()s to
          the appropriate atomic(9) operations.
        - Only walk the descriptor chain when freeing if INVARIANTS is
          defined since the result is only KASSERT()ed.
