[PATCH] PCI: pci-keystone-dw: remove some unused variables

[Shawn Lin <shawn.lin@xxxxxxxxxxxxxx>]

We got the following warning:

drivers/pci/dwc/pci-keystone-dw.c: In function
'ks_dw_pcie_msi_irq_mask':

drivers/pci/dwc/pci-keystone-dw.c:171:24: warning: variable 'ks_pcie'
set but not used [-Wunused-but-set-variable]

drivers/pci/dwc/pci-keystone-dw.c: In function
  'ks_dw_pcie_msi_irq_unmask':

drivers/pci/dwc/pci-keystone-dw.c:194:24: warning: variable 'ks_pcie'
  set but not used [-Wunused-but-set-variable

By looing into the code, ks_pcie and pci variables are never used.
Remove them to silent the compile warning.
