i40e: remove BUG_ON from feature string building

Browse source

There's really no reason to kill the kernel thread just because of a
little info string. This reworks the code to use snprintf's limiting to
assure that the string is never too long, and WARN_ON to still put out
a warning that we might want to look at the feature list length.

Prompted by a recent Linus diatribe.
