qcacld-3.0: Add pointer check before dereferencing 

Make sure the parsed association request array is valid at the
association ID index, before dereferencing it. This will prevent NULL
pointer deref. There is already a check for the beginning of the parsed
assoc req array, but it is not checking at the assoc ID index.
