qcacld-3.0: Fix PMF SAP not sending SA query for duplicate req

In case STA is in connected state, and the PMF SAP receive Assoc
request from the STA, the assoc request is silently dropped.
Instead the SAP should send assoc resp with comeback time and
start SA query.

Fix it by not dropping the duplicate assoc request frame for PMF
capable STA.
