Bluetooth: Fix bogus check for re-auth no supported with non-ssp

Browse Source 
This reverts 19f8def031
"Bluetooth: Fix auth_complete_evt for legacy units" which seems to be
working around a bug on a broken controller rather then any limitation
imposed by the Bluetooth spec, in fact if there ws not possible to
re-auth the command shall fail not succeed.
