wlan: Fix possible buffer overflow in sirConvertAddtsRsp2Struct

In the function sirConvertAddtsRsp2Struct, iterator j is
assigned with the value pAddTs->numTclas + addts.num_WMMTCLAS.
The j value is used as the index to the array pAddTs->tclasInfo.
Maximum limit on  pAddTs->tclasInfo entries is 2. So when the
value of j exceeds 2, then a possible buffer overflow could
occur.

Validate the value of j against SIR_MAC_TCLASIE_MAXNUM(2).
