PCI: xilinx: Fix xilinx_pcie_assign_msi() return value test
We should be testing "hwirq" instead of "irq". "irq" is unsigned so it's never less than zero. Also it's uninitialized. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Srikanth Thokala <sthokal@xilinx.com>
