Josef Johansson 2b96f92ca4 PCI/MSI: Correct 'can_mask' test in msi_add_msi_desc() 
71020a3c0d ("PCI/MSI: Use msi_add_msi_desc()") inadvertently reversed
the sense of "msi_attrib.can_mask" in one use:

  - if (entry->pci.msi_attrib.can_mask) {
  -         addr = pci_msix_desc_addr(entry);
  -         entry->pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);
  + if (!desc.pci.msi_attrib.can_mask) {
  +         addr = pci_msix_desc_addr(&desc);
  +         desc.pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);

Restore the original test.
