vswitch: Set minimum probe interval to 5 seconds

In vSwitch, the minimum probe interval is supposed to be 5 seconds, but
that was not enforced.  If no interval was specified in the config file,
a value of 0 was being used, which would cause probes to never be sent
and the rconn not to move out of its ACTIVE state.

Possible fix to Bug #1466.
