Subject: [PATCH AUTOSEL 6.4 03/10] Revert "wifi: ath11k: Enable threaded NAPI"

From: Kalle Valo <quic_kvalo@...cinc.com>

[ Upstream commit d265ebe41c911314bd273c218a37088835959fa1 ]

This reverts commit 13aa2fb692d3717767303817f35b3e650109add3.

This commit broke QCN9074 initialisation:

[  358.960477] ath11k_pci 0000:04:00.0: ce desc not available for wmi command 36866
[  358.960481] ath11k_pci 0000:04:00.0: failed to send WMI_STA_POWERSAVE_PARAM_CMDID
[  358.960484] ath11k_pci 0000:04:00.0: could not set uapsd params -105

As there's no fix available let's just revert it to get QCN9074 working again.
