[PATCH 1/4] wifi: ath10k: clear monitor interface after add failure

[Jiale Yao <yaojiale02@163.com>]

ath10k_add_interface() publishes the monitor vif before recalculating the
monitor configuration. If that operation fails, the interface addition is
unwound but monitor_arvif still points at the vif that mac80211 will free.

Clear the published pointer before entering the common vdev cleanup path.
