xen/pciback: Check PF instead of VF for PCI_COMMAND_MEMORY
commit 8d47065f7d1980dde52abb874b301054f3013602 upstream.
Commit 408fb0e5aa7fda0059db282ff58c3b2a4278baa0 (xen/pciback: Don't
allow MSI-X ops if PCI_COMMAND_MEMORY is not set) prevented enabling
MSI-X on passed-through virtual functions, because it checked the VF
for PCI_COMMAND_MEMORY but this is not a valid bit for VFs.
Instead, check the physical function for PCI_COMMAND_MEMORY.
