qcacld-3.0: Delete PMF Sta from previous vdev

qcacld-2.0 to qcacld-3.0 propagation

If a PMF Sta is already connected to one interface and try
to switch to other interface without sending deauth/disassoc,
sta entry is not deleted from previous vdev and one more entry
is created on current vdev. Due to this htt is not able to get
valid peer for EAPOL packets and EAPOL packets are dropped leading
to connection failure.
To fix this, Add check to delete PMF Sta from one vdev when
assoc request is received on another vdev.
