Title: OVSDriver: workaround kernel errno bug

Reviewer: @poolakiran

Older versions of the openvswitch kernel module had a bug where they returned
garbage errno values in case of success.

This change ports the workaround already in ivs-ctl to the OVSDriver transact
utility method. It also increases the range of valid errnos based on
MAX_ERRNO in the kernel source.
