wlan: Prevent purging of sme pending commands

As a part of wlan exit, HDD sent below commands
to sme.
1) Full Power Request
2) Disconnect Req (DelBSS /Del Sta)
3) Close Session ( DelSelfSta ).
But when MC thread get block, all these commands added into
SME pending queue. When csr perform Close session, CSR purge
all the pending commands. Hence DelSelfSTA goes without DelBss
/Del Sta which is not expected sequence by firmware.

In this fix purging of command will be perform bit ahead,
so all essential command go to firmware before sending
DelSelfSta.
