Upon firmware assert, restart work will be triggered so that mac80211 will reconfigure the driver. An issue is reported that after restart work, survey dump data do not contain in-use (SURVEY_INFO_IN_USE) info for operating channel. During reconfigure, since mac80211 already has valid channel context for given radio, channel context iteration return num_chanctx > 0. Hence rx_channel is always NULL. Fix this by assigning channel context to rx_channel when driver restart is in progress.
