[ Upstream commit 40ed054f39bc99eac09871c33198e501f4acdf24 ]
dm-flakey would error all IOs if num_features was 0, but if it was
absent, dm-flakey would never error any IO. Fix this so that no
num_features works the same as num_features set to 0.
Fixes: aa7d7bc99f ("dm flakey: add an "error_reads" option")

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.
