[PATCH] NTB: EPF: Mark pci_read and pci_write as static

[Souptick Joarder]

From: "Souptick Joarder (HPE)" <jrdr.linux@xxxxxxxxx>

kernel test robot throws below warning ->

drivers/pci/endpoint/functions/pci-epf-vntb.c:975:5: warning:
no previous prototype for 'pci_read' [-Wmissing-prototypes]
drivers/pci/endpoint/functions/pci-epf-vntb.c:984:5: warning:
no previous prototype for 'pci_write' [-Wmissing-prototypes]

mark them as static.
