ovs-vsctl: Remove default timeout.

On overloaded XenServers the current default timeout of 5 seconds can
occasionally be reached, which causes VM startup to fail.  This commit
fixes the problem by removing the default timeout and changing each
invocation of ovs-vsctl within the tree to specify its own timeout,
if appropriate.

Bug #3573.
