Some drivers (such as virtio) may need to read more than 4 bytes
data from PCI configuration space via rte_eal_pci_read_config().
But it will return with an error on FreeBSD when the expected
data length is bigger than the size of pi.pi_data whose type is
u_int32_t. This patch removes this limitation.
