When scsi_dma_map() fails by returning a sges_left value less than zero, the amount of logging produced can be extremely high. In a recent end-user environment, 1200 messages per second were being sent to the log buffer. This eventually overwhelmed the system and it stalled. These error messages are not needed. Remove them.

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.
