media: uvcvideo: Shorten the transfer size non compliance message

This message is much longer than others and doesn't fit even in a 160
column window when printed, despite providing little real information.

Also replace 'transmission' with 'transfer' because that's the actual
name and 'max packet' with 'limit' because it isn't same thing with
isochronus endpoints. Remove cryptic abbreviations like 'ep'.
