Nirbhay Choubey 48a0a66ffa MDEV-10186: mysqld crash when runtime setting wsrep_cluster_address without wsrep_on=ON

On wsrep_cluster_address update, node restarts the replication
and attempts to connect to the new address. In this process it
makes a call to wsrep provider's connect API, which could lead
to segfault if wsrep provider is not loaded (wsrep_on=OFF).

Fixed by making sure that it proceeds only if a provider is
loaded.
