Summary

nd6_prefix_onlink will enter net_epoch when necessary.
Also, exit net_epoch earlier in nd6_prefix_onlink,
Because we acquired a reference to ifa, and we got our ifa
from the pr->ndpr_ifp, we don't need to stay under epoch.
While here, style it.

1420	This change looks good to me.
2168	I'd recommend against this. A recursive `NET_EPOCH_ENTER()` has less performance impact vs a re-enter epoch. CC @glebius for this change.
