qcacld-3.0: Fix filling peer mac in lim_prepare_and_send_deauth

Peer mac is filled from struct wlan_cm_vdev_discon_req, which
can be 0 or previous AP in case of roaming.
While handling disconnect the bssid and peer mac needs to be copied
from pe session for STA mode to avoid this mismatch and thus
disconnect failure.

Peer mac updating from pe session was missed, so to fix the issue
populate the peer mac from pe session.
