pci: do not check BAR0 mapping
pci: do not check BAR0 mapping

Since DPDK 1.4, bars mapping is checked and prevent from initializing
drivers which do not use igb_uio mapping (see commit eee16c964cd).

There is no need to check for bars mapping, especially BAR0 is not required.
If bars mapping failed, then pci_uio_map_resource will fail and we won't reach
this check. So get rid of BAR0 check.
