Bluetooth: Move IRK checking logic in preparation to new connect method
Move IRK checking logic in preparation to new connect method. Also make sure that MGMT_STATUS_INVALID_PARAMS is returned when non identity address is passed to ADD_DEVICE. Right now MGMT_STATUS_FAILED is returned, which might be misleading. Signed-off-by: Jakub Pawlowski <jpawlowski@google.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
