Adding the bond device as its own slave should be forbidden. This
will cause a recursive endless loop in many subsequent operations,
and eventually lead to coredump.
This problem was found in testpmd, the related logs are as follows:
testpmd> create bonded device 1 0
Created new bonded device net_bonding_testpmd_0 on (port 4).
testpmd> add bonding slave 4 4
Segmentation fault (core dumped)
