[ Upstream commit8ceca59fb3] The content of the TX desc is automatically cleared by the HW when the HW has sent out the packet to the wire. When desc filling fails in hns3_nic_net_xmit(), it will call hns3_clear_desc() to do the error handling, which miss zeroing of the TX desc and the checking if a unmapping is needed. So add the zeroing and checking in hns3_clear_desc() to avoid the above problem. Also add DESC_TYPE_UNKNOWN to indicate the info in desc_cb is not valid, because hns3_nic_reclaim_desc() may treat the desc_cb->type of zero as packet and add to the sent pkt statistics accordingly.

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.
