pci: do not manually unmap resources if probe fails

Browse Source 
We need to do it only for DPDK 16.11, which leaks the
mappings otherwise. DPDK was fixed in version 17.02 with
the following commit:

e84ad157 (pci: unmap resources if probe fails)

Unmapping the resources twice doesn't actually cause
us any trouble, but prints an ambiguous error message.
