[PATCH 3/7] wifi: ath12k: add no-op without debug print in WMI Rx event

[Kalle Valo]

From: Aditya Kumar Singh <quic_adisi at quicinc.com>

Currently, certain WMI events are frequently received by the host. Since
the host lacks the logic to process these events, the console is flooded
with ‘Unknown eventid:’ debug messages.

To address this, handle these events gracefully without printing debug
messages. There is already a block of event IDs that are ignored with a debug
print. However, this new type of event occurs more frequently, so no debug
print is necessary, and handling it should be a no-op.

While at it, re-arrange the code so that all Unknown event IDs are towards
the end of the switch block.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
