rcu-tasks: Disable and enable CPU hotplug in same function

The rcu_tasks_trace_pregp_step() function invokes cpus_read_lock() to
disable CPU hotplug, and a later call to the rcu_tasks_trace_postscan()
function invokes cpus_read_unlock() to re-enable it.  This was absolutely
necessary in the past in order to protect the intervening scan of the full
tasks list, but there is no longer such a scan.  This commit therefore
improves readability by moving the cpus_read_unlock() call to the end
of the rcu_tasks_trace_pregp_step() function.  This commit is a pure
code-motion commit without any (intended) change in functionality.
