bonding: use return instead of goto
Replace 'goto' with 'return' to remove unnecessary check at label: err_undo_flags. The reason is that 'err_undo_flags' do two things for the first slave device: 1.revert bond mac address if it is set by the slave device. 2.revert bond device type if it's not ARPHRD_ETHER. It's not necessary for the following three places, they changed neither bond mac address nor type. It's straightforward to return directly.
