hang during shutdown in next-20260722+ with MT7925

[Bert Karwatzki]

Since next-20260722 my debian sid system hangs when shutting down or
rebooting (No error message when monitoring the shutdown process via
netconsole). I bisected the error to commit
13b7e6a96a00 ("wifi: mt76: Disable napi when removing device")
and reverting this commit in next-20260723 makes shutting down or
rebooting work normally again.
