media: vb2: frame_vector.c: replace WARN_ONCE with a comment
The WARN_ONCE was issued also in cases that had nothing to do with VM_IO (e.g. if the start address was just a random value and uaccess fails with -EFAULT). There are no reports of WARN_ONCE being issued for actual VM_IO cases, so just drop it and instead add a note to the comment before the function.

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.
