The pointer batadv_bla_claim::backbone_gw can be changed at any time. Therefore, access to it must be protected to ensure that two function accessing the same backbone_gw are actually accessing the same. This is especially important when the crc_lock is used or when the backbone_gw of a claim is exchanged.
Not doing so leads to invalid memory access and/or reference leaks.

Hm, this doesn't look really correct. Maybe we should drop this for now.
Kind regards, Sven
