PCI: endpoint: pci-epf-test: Remove superfluous code

The only reason why we call pci_epf_configure_bar() is to set
PCI_BASE_ADDRESS_MEM_TYPE_64 in case the hardware requires it.

However, this flag is now automatically set when allocating a BAR that
can only be a 64-bit BAR, so we can drop pci_epf_configure_bar()
completely.
