Sergey Nemov d510497b83 i40e: add input validation for virtchnl handlers
Change some data to unsigned int instead of integer when we compare.

Check LUT values in VIRTCHNL_OP_CONFIG_RSS_LUT handler.

Also enhance error/warning messages to print the real values of
I40E_MAX_VF_QUEUES, I40E_MAX_VF_VSI and I40E_DEFAULT_QUEUES_PER_VF
instead of plain text.

Refactor code to comply with 'check first then assign' policy.

Remove duplicate checks for VIRTCHNL_OP_CONFIG_RSS_KEY and
VIRTCHNL_OP_CONFIG_RSS_LUT opcodes in i40e_vc_process_vf_msg(). We have
the very same checks inside the handlers already.

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.
