openvswitch-switch.init: Redirect error to /dev/null.

The latest Open vSwitch kernel module from Upstream linux does not list "version". During debian package installation, we would see a non-harmful error in the log. This patch suppresses it. Signed-off-by: Gurucharan Shetty <[email protected]> Acked-by: Ben Pfaff <[email protected]>
