wlan: Avoid DEL_STA_SELF when Disconnecting SAP

At the time of START AP driver sends ADD_STA_SELF
followed with ADD BSS.
After that driver do DEL_BSS followed with DEL_STA_SELF.
In case of SAP, firmware add self address as BSS address.

In sapFsm, sme_CloseSession will call limProcessSmeDelStaSelfReq to
do DEL_STA_SELF. Firmware returns failure for DEL_STA_SELF as this
was already deleted as part of DEL_BSS.
Fix is to not send DEL_STA_SELF for SAP scenario
Instead of this driver will do only csrCleanupSession and will post
eSAP_STOP_BSS_EVENT to HDD to STOP BSS.
