This fixes missing guards on trying to calculate a checksum with an invalid/unknown checksum type; moving the guards up to e.g. btree_io.c might be "more correct", but doesn't buy us anything - an unknown checksum type will always be flagged as at least a checksum error so we aren't losing any safety doing it this way and it makes it less likely to accidentally pop an assert we don't want.

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 reStructuredText 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.
