ovs-lib: dont't purge corrupted DB

In ovs-lib there is a function named upgrade_db which tries to convert a
database after OVS {up,down}grades. This function uses ovsdb-tool to
check if the DB needs to be upgraded. If the upgrade fails,
it purges the DB and create an empty one.
ovsdb-tool returns "yes" or "no" to indicate if the DB needs upgrading,
but if the DB is corrupted it returns a list of errors.
Change a condition from "!= no" to "= yes" because in case of DB
corruption upgrade_db would purge the existing DB without writing
anything in the logs.
