Make pci-epf-test use pci_epc_get_next_free_bar() just like pci-epf-ntb.c and pci-epf-vntb.c. Using pci_epc_get_next_free_bar() also makes it more obvious that pci-epf-test does no special configuration at all. (The only configuration pci-epf-test does is setting PCI_BASE_ADDRESS_MEM_TYPE_64 if epc_features has marked the specific BAR as only_64bit. pci_epc_get_next_free_bar() already takes only_64bit into account when looping.) This way, the code is more consistent between EPF drivers, and pci-epf-test does not need to explicitly check if the BAR is reserved, or if the index belongs to a BAR succeeding a 64-bit only BAR.
