fix openvswitch requirement check

With VXLAN enabled on openvswitch, neutron checks
module version of the openvswitch kernel module.
If the pattern to extract the version matches twice
(eg. for path and version) the agent dies.

This patch ensures, that only the version is checked
against the pattern.
