qcacld-3.0: Fix WAPI IoT issue

DUT can't connect some WAPI AP by ASCII due to
lim_process_assoc_rsp_frame: received Re/AssocRsp frame failure code:
40.
Current Some WAPI AP cannot accept Vendor Element ID:  221  length > 11,
and  reply reject ASSOC resp by reason code 40.
Because we extend Vendor Specific element to include MCS12/13 from HSP.
So only HSP meet this IOT issue.
Qualcomm Inc. - Specific
    Element ID:         221  Vendor Specific [71]
    Length:             15 [72]
    OUI:                8C-FD-F0 [73-75]
