qcacld-2.0: During unload avoid sending disconnect twice for IBSS

When leave ibss is called, disconnect ibss command is posted to
SME and leave ibss function returns without waiting for disconnect
to get complete.

Now if unload is started before ibss disconnect is completed, as
part of stop adapter again ibss disconnect command is posted to SME
as HDD state is still not disconnected.

The first disconnect sets the BSSID to zero and thus once second
disconnect calls disconnect handler, warning is seen as BSSID passed
to ipa event handler is zero.

As part of fix add wait for disconnect completion in leave ibss and
move the BSSID check after SAP device mode check.
