Fix an issue detected by the Smatch tool: sound/soc/sof/ipc4-pcm.c: sof_ipc4_pcm_dai_link_fixup_rate() error: uninitialized symbol 'be_rate'. The warning highlights a case where `be_rate` could remain uninitialized if `num_input_formats` is zero, which would cause undefined behavior when setting `rate->min` and `rate->max` based on `be_rate`. To address this issue, a `WARN_ON_ONCE(!num_input_formats)` check was added to ensure `num_input_formats` is greater than zero. If this condition fails, the function returns `-EINVAL`, preventing the use of an uninitialized `be_rate`. This change improves the robustness of the function by catching an invalid state early and providing better feedback during development.

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.
