PCI/IOV: Mark VFs as not implementing PCI_COMMAND_MEMORY
For VFs, the Memory Space Enable bit in the Command Register is
hard-wired to 0.
Add a new bit to signify devices where the Command Register Memory
Space Enable bit does not control the device's response to MMIO
accesses.
Fixes: abafbc551fdd ("vfio-pci: Invalidate mmaps and block MMIO access on disabled memory")
