Tested with running testpmd using -a 27:00.0 -a 27:00.1 and then using
dpdk-proc-info with the same ports prefixed with 0000:. Without this patch,
that gave an error. With this patch, output was the same with and without
the extra prefix.
Also tested the reverse case, running testpmd with the domain prefix, and
proc-info without, that too worked in testing.
