snd_usb_find_clock_source and snd_usb_find_clock_selector are helper macros that
look at an entity id and validate that this entity id is in fact a clock source
or a clock selector. The present comments inside __uac_clock_find_source give
the reader the impression we're looking for an entity id.
We're looking for an entity id indeed, the clock source, but since
__uac_clock_find_source is recursive, we're also looking *at* the entity ids,
in the search for the one clock source.
Fix the comment so we don't give readers a wrong idea.
