Wen Gong a20ed60bb3 wifi: ath11k: fix failed to find the peer with peer_id 0 when disconnected 
It has a fail log which is ath11k_dbg in ath11k_dp_rx_process_mon_status(),
as below, it will not print when debug_mask is not set ATH11K_DBG_DATA.
	ath11k_dbg(ab, ATH11K_DBG_DATA,
		  "failed to find the peer with peer_id %d\n",
		   ppdu_info.peer_id);

When run scan with station disconnected, the peer_id is 0 for case
HAL_RX_MPDU_START in ath11k_hal_rx_parse_mon_status_tlv() which called
from ath11k_dp_rx_process_mon_status(), and the peer_id of ppdu_info is
reset to 0 in the while loop, so it does not match condition of the
check "if (ppdu_info->peer_id == HAL_INVALID_PEERID" in the loop, and
then the log "failed to find the peer with peer_id 0" print after the
check in the loop, it is below call stack when debug_mask is set
ATH11K_DBG_DATA.

The reason is this commit 01d2f285e3 ("ath11k: decode HE status tlv")
add "memset(ppdu_info, 0, sizeof(struct hal_rx_mon_ppdu_info))" in
ath11k_dp_rx_process_mon_status(), but the commit does not initialize
the peer_id to HAL_INVALID_PEERID, then lead the check mis-match.

Callstack of the failed log:

Reset the default value to HAL_INVALID_PEERID each time after memset

ath11k_dp_rx_process_mon_status(), then the failed log disappeared.

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 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.
