Subject: [PATCH] NTB: EPF: reduce several globals to statics

sparse reports
drivers/pci/endpoint/functions/pci-epf-vntb.c:956:10: warning: symbol 'pci_space' was not declared. Should it be static?
drivers/pci/endpoint/functions/pci-epf-vntb.c:975:5: warning: symbol 'pci_read' was not declared. Should it be static?
drivers/pci/endpoint/functions/pci-epf-vntb.c:984:5: warning: symbol 'pci_write' was not declared. Should it be static?
drivers/pci/endpoint/functions/pci-epf-vntb.c:989:16: warning: symbol 'vpci_ops' was not declared. Should it be static?

These functions and variables are only used in pci-epf-vntb.c, so their storage
class specifiers should be static.

Fixes: ff32fac00d97 ("NTB: EPF: support NTB transfer between PCI RC and EP connection")
