msm: pcie: Fix macro compiler warning for pci-msm.c

Fix a few warnings that seem to be related to improper argument
concatenation in the macros:

 drivers/pci/controller/pci-msm.c:246:4: error:
   too many arguments for format [-Werror=format-extra-args]
 drivers/pci/controller/pci-msm.c:248:34: error:
   too many arguments for format [-Werror=format-extra-args]

Fixes: 42576b8a ("msm: pcie: add PCIe root complex bus driver snapshot")
