bthost: Fix not initializing address types properly

The address type given to the init_conn is the peer address type
(btdev) not the bthost address type, the old code assume it could use
since only BDADDR_BREDR or BDADDR_LE_PUBLIC was tested but with the
upcoming support for LL Privacy the peer address type would become
BDADDR_LE_RANDOM which cannot be used as address type of bthost as that
doesn't support random addresses and would likely cause SMP to fail when
pairing.
