On Linux kernel 4.1, `ip link` reports peer interface name for
each Open vSwitch interface, like:
$ ip link
...
71: ovs-tap1@brbm-tap1: <BROADCAST,MULTICAST,UP,LOWER_UP> ...
~~~~~~~~~~
Currently it is regarded as a part of interface name, so
causes failure in tap id detection from ovs-vsctl output,
that results into ironic deployment failure.
This patch removes the peer name from the interface name.
