Colin Ian King 66c6afbd73 nvmet: fix comparison of a u16 with -1
Currently the u16 req->error_loc is being compared to -1 which
will always be false.  Fix this by casting -1 to u16 to fix this.

Detected by clang:
  warning: result of comparison of constant -1 with expression of
  type 'u16' (aka 'unsigned short') is always false
  [-Wtautological-constant-out-of-range-compare]

Fixes: 76574f37bf ("nvmet: add interface to update error-log page")

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.
