When callbacks are offloaded, the NOCB kthreads handle the callbacks progression on behalf of rcu_core(). However during the (de-)offloading process, the kthread may not be entirely up to the task. As a result some callbacks grace period sequence number may remain stale for a while because rcu_core() won't take care of them either. Fix this with forcing callbacks acceleration from rcu_core() as long as the offloading process isn't complete.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
