Check if devcom holds an error pointer and return immediately.
This fixes Smatch static checker warning:
drivers/net/ethernet/mellanox/mlx5/core/lib/sd.c:221 sd_register()
error: 'devcom' dereferencing possible ERR_PTR()
Enhance mlx5_devcom_register_component() so it stops returning NULL,
making it easier for its callers.

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.
