[SCSI] csiostor: Use pcie_capability_clear_and_set_word() to simplify code
pci_is_pcie() and pcie_capability_clear_and_set_word() make it trivial
to set the PCIe Completion Timeout, so just fold the
csio_set_pcie_completion_timeout() function into its caller.
[bhelgaas: changelog, fold csio_set_pcie_completion_timeout() into caller]
