ASoC: SOF: ipc3-loader: 'Handle' PROBE_INFO ext_manifest type when parsing

Every time when the firmware is loaded we see the following printed in
info level:
unknown sof_ext_man header type 3 size 0x30

This is the PROBE_INFO element, which is not parsed, but it is not
something that we should treat as surprise, aka unknown type.

Add an empty case with a debug print to 'handle' this ext_manifest type and
silence the confusing print in kernel log.
