qcacld-3.0: Reset vdev_to_iface QDF_IPA_STA_DISCONNECT

Browse Source 
In __wlan_ipa_wlan_evt, for QDF_IPA_STA_DISCONNECT event,
ipa_ctx->vdev_to_iface[session_id] is reset back to
WLAN_IPA_MAX_SESSION only when ipa_ctx->sap_num_connected_sta
is greater than 0. So, in STA+SAP concurrency case, when
no client is connected to SAP, if STA is disconnected,
vdev_to_iface is not reset for that particular session id,
making it unusable for further events involving IPA iface
creation.

Fix is to move the code to reset vdev_to_iface outside the check
for ipa_ctx->sap_num_connected_sta in QDF_IPA_STA_DISCONNECT
scenario, so that vdev_to_iface is reset irrespective of SAP.
