bonding: mc addresses don't get deleted on enslave failure

nikolay@redhat.com · davem330 · commit 25e40305d4f4 · 2013-04-19T17:48:18.000-04:00
Add bond_mc_list_flush() after err_detach as that's the first error path
after the addresses are added. The main issue is the mc addresses' refcount
which only gets bumped up.

v2: update log message and don't move code unnecessarily
