bridge: fix error handling in br_add_if()
When device is added to bridge its refcnt is incremented (in new_nbp()), but if error occurs during further br_add_if() operations this counter is not decremented back. Fix it by adding dev_put() call in the error path. Signed-off-by: Volodymyr G Lukiianyk <volodymyrgl@gmail.com> Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
