Frederic Weisbecker 314202f84d rcu/nocb: Flush bypass before setting SEGCBLIST_SOFTIRQ_ONLY ...

This commit flushes the bypass queue and sets state to avoid its being
refilled before switching to the final de-offloaded state.  To avoid
refilling, this commit sets SEGCBLIST_SOFTIRQ_ONLY before re-enabling
IRQs.
