pci: set PCI memory enable before mapping PCI BAR

This change mitigates software faults issued by some versions of the
linux kernel vfio-pci driver when VF PCI BARs are used without setting
the memory enable bit in the PCI configuration. This problem is
mentionned in https://lkml.org/lkml/2020/6/25/628
