[ Upstream commit 326334aad024a60f46dc5e7dbe1efe32da3ca66f ]
The tqp_index is received from vf, if use it directly,
an out-of-bound issue may be caused, so add a check for
this tqp_index before using it in hclge_get_ring_chain_from_mbx().

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.
