qcacld-3.0: Fix SME command stuck issue

If ADD TS is sent it will be an active command in SME till driver gets
resp from peer or timeout. During this phase if LFR3 roam sync event is
received from firmware then PE session cleanup will be done and
SME/CSR is updated with new BSS info. In LIM, 'gLimAddtsSent' flag is
set while processing add tspec request and 'gLimAddtsSent' flag will be
reset once add tspec response received or addts rsp timeout.
This timeout doesn't expire because as part of LFR3 roam sync,
PE delete session is done which stops the timer. Because of this
'gLimAddtsSent' flag is not reset and add tspec response is not sent to
SME, this blocks further SME commands as addts req is not removed from
the active command list. This also blocks PE msg processing as
gLimProcessDefdMsgs is set to FALSE when addts request is sent.
This is not reset as the timer is killed as part of pe delete session.

To address this issue, call lim_process_sme_addts_rsp_timeout()
to reset the 'gLimAddtsSent' flag and send addts rsp timeout to SME.
