[PATCH 06/10] wifi: ath12k: allow specific mgmt frame tx while vdev is not up

[Kang Yang]

In current code, the management frames must be sent after vdev is started.
But for P2P device, vdev won't start until P2P negotiation is done. So
this logic doesn't make sense for P2P device.

Also use ar->conf_mutex to synchronize vdev delete and mgmt, TX.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
