Add STATUS_INFO_LENGTH_MISMATCH mapping to EMSGSIZE. Currently, STATUS_INFO_LENGTH_MISMATCH has no mapping to any error code, making it difficult to distinguish between invalid parameters and length mismatch. Map STATUS_INFO_LENGTH_MISMATCH to EMSGSIZE while keeping the EINVAL for invalid parameters. Although the buf_len check only checks for buf_size being less than required, there was no error code for lower buf_size. Hence, EMSGSIZE is used.

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.
