qcacmn: Change minimum mbssid ie length value to 1

Browse Source 
Currently, in the driver, the minimum MBSSID IE length value
in the driver is set to 4. Some APs advertize this value as
1. In such situations, driver fails to parse the the ie.
So, to avoid such cases, modify the minimum mbssid ie length
value to 1.
