Karthikeyan Kathirvel e1bdff48a1 wifi: ath12k: fix out-of-bound access of qmi_invoke_handler() 
Currently, there is no terminator entry for ath12k_qmi_msg_handlers hence
facing below KASAN warning,

 ==================================================================
 BUG: KASAN: global-out-of-bounds in qmi_invoke_handler+0xa4/0x148
 Read of size 8 at addr ffffffd00a6428d8 by task kworker/u8:2/1273

 The address belongs to the variable:
  ath12k_mac_mon_status_filter_default+0x4bd8/0xfffffffffffe2300 [ath12k]
 [...]
 ==================================================================

Add a dummy terminator entry at the end to assist the qmi_invoke_handler()
in traversing up to the terminator entry without accessing an
out-of-boundary index.

README 

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.
