Subject: [PATCH] pcm: route: Fix use_getput flag computation for 3 byte
 formats

Commit de63b942acf520 ("pcm: route: Use get/put labels for all 3 byte formats")
wanted to make the route plugin use get / put labels not only for 24-bit
physical width formats but also for 18 and 20-bit ones.
There was, however, a typo in that commit so a check for these widths
didn't really work.

Let's fix it now.
