Bluetooth: Fix warning of potentially uninitialized adv_instance variable
Rework the logic of checking for a valid adv_instance for non-zero cp->instance values. Without this change we may get (false positive) warnings as follows: >> net/bluetooth/mgmt.c:7294:29: warning: 'adv_instance' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
