rcu: Comment why callbacks migration can't wait for CPUHP_RCUTREE_PREP
The callbacks migration is performed through an explicit call from
the hotplug control CPU right after the death of the target CPU and
before proceeding with the CPUHP_ teardown functions.
This is unusual but necessary and yet uncommented. Summarize the reason
as explained in the changelog of:
a58163d8ca2c (rcu: Migrate callbacks earlier in the CPU-offline timeline)
