[PATCH 06/11] rcu/nocb: Remove halfway (de-)offloading handling from bypass

[Frederic Weisbecker <frederic@kernel.org>]

Bypass enqueue can't happen anymore in the middle of (de-)offloading
since this sort of transition now only applies to offline CPUs.

The related safety check can therefore be removed.
