bus/pci: harmonize return value of config read

On Linux, rte_pci_read_config on success returns the number of read
bytes, but on BSD it returns 0.
Document the return values, and have BSD behave as Linux does.

At least one case (bnx2x PMD) treats 0 as an error, so the change
makes sense also for that.
