qcacmn: Skip chanlist event during recovering

Add new qdf API: qdf_is_recovering and
qdf_register_recovering_state_query_callback.
Client driver will register the state query callback
to common driver to report the recovering state.

Regulatory skip the chanlist update event during SSR
to keep the current regulatory setting.
