qcacld-3.0: Wait for roam to get stopped during disconnect
In case roaming was in progress when hdd_disconnect was called, avoid
defer disconnect as that will call hdd api in mcthread which waits on
event for about 5 seconds thus blocking everything. Also defer disconnect
makes supplicant and driver state go out of sync. Rather wait in hdd
for roaming to complete and then issue disconnect keeping state simple
and clean
