[ovs-dev] [PATCH] ovs-save: Fix awk command to return highest ofp version.

[lin huang]

The quotes for strings like "br0" had been removed.In ovs-save file
get_highest_ofp_version function still using quotes as field separator.
That is, get_highest_ofp_version() always return OpenFlow14 version string,
not the highest ofp version.

This patch adds support for new string style to return highest ofp version.
