bool notify is referenced nowhere else in the function except to check
whether or not to call rtnl_offload_xstats_notify(). Remove it and move
the call to the previous branch.

Thanks Dennis,

This looks like a nice clean-up to me.

I guess this is an artefact of the development of this code as this pattern
has been present since the code was added by Petr Machata (CCed) in
commit 1a6d7ae7d63c ("netdevsim: Introduce support for L3 offload xstats").

Thanks for the CC!

There was some locking / cleanup business originally that necessitated
the variable. That went away during internal review, but this was left
behind. I agree it can be cleaned up.
