During a realtime grow operation, we run a single transaction for each rt bitmap block added to the filesystem. This means that each step has to be careful to increase sb_rblocks appropriately. Fix the integer overflow error in this calculation that can happen when the extent size is very large. Found by running growfs to add a rt volume to a filesystem formatted with a 1g rt extent size.

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.
