i2c: mux: demux-pinctrl: do not deactivate a master that is not active
Attempting to rollback the activation of the current master when the current master has not been activated is bad. priv->cur_chan and priv->cur_adap are both still zeroed out and the rollback may result in attempts to revert an of changeset that has not been applied and do result in calls to both del and put the zeroed out i2c_adapter. Maybe it crashes, or whatever, but it's bad in any case.
