MFC r287564:

  isci: check return value of pci_alloc_msix()

  Certain VM guest types (VMware, Xen) do not support MSI, so pci_alloc_msix()
  always fails.  isci(4) was not properly detecting the allocation failure,
  and would try to proceed with MSIx resource initialization rather than
  reverting to INTx.
