Subject: [PATCH 025/120] mtk: wifi: mt76: mt7996: support record muru algo log
 when record fw log

Support record muru algorithm debug log in firmware when we use
chihuahua tool to record fw log. This can help us to check some key
point of muru algorithm result, like bsrp status, airtime busy status,
ru candidate...
Corresponding to Logan driver, it is the same as execute the iwpriv
command: iwpriv rax0 set muruDbgInfo=[category]-1

Disable muru debug log when we stop record fwlog. Without this commit,
if we run $ echo 2 > fw_debug_wm after recording fwlog, it will print
out too many fw debug log.
