net/bonding: fix PCI address comparison on non-PCI ports

The bonding PMD will iterate over all available ETH ports and for each,
compare a chunk of bytes at an offset that would correspond to the PCI
address in an rte_pci_device.

This is incorrect and unsafe. Also, the rte_device using this PCI
address is already found, no need to compare again the PCI address of
all eth devices.

Refactoring the code to fix this, the initial check to find the PCI bus
is out of scope.
