> Log:
>   Fix synchronization of LB group access.
>
>   Lookups are protected by an epoch section, so the LB group linkage must
>   be a CK_LIST rather than a plain LIST.  Furthermore, we were not
>   deferring LB group frees, so in_pcbremlbgrouphash() could race with
>   readers and cause a use-after-free.
