The null check of filp->f_path.dentry->d_iname is redundant because
it is an array of DNAME_INLINE_LEN chars and cannot be a null. Fix
this by removing the null check.
Addresses-Coverity: ("Array compared against 0")
Fixes: 04987ca1b9 ("net: hns3: add debugfs support for tm nodes, priority and qset info")

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.
