Deren Wu 0ffcb2a68b wifi: mt76: fix coverity uninit_use_in_call in mt76_connac2_reverse_frag0_hdr_trans()
The default case for frame_contorl is invalid. We should always
assign addr3 of this frame properly.

Coverity error message:
if (ieee80211_has_a4(hdr.frame_control))
(19) Event uninit_use_in_call:	Using uninitialized value "hdr".
Field "hdr.addr3" is uninitialized when calling "memcpy".
	memcpy(skb_push(skb, sizeof(hdr)), &hdr, sizeof(hdr));
else
	memcpy(skb_push(skb, sizeof(hdr) - 6), &hdr, sizeof(hdr) - 6);

Fixes: 0880d40871 ("mt76: connac: move mt76_connac2_reverse_frag0_hdr_trans in mt76-connac module")

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.
