An initial commit to add tracepoints for packets without CIP headers
uses different print formats for added tracepoints. However this is not
convenient for users/developers to prepare debug tools.
This commit uses the same format for the two tracepoints.

Fixes: b164d2fd6e ('ALSA: firewire_lib: add tracepoints for packets without CIP headers')
