[PATCH] staging: exfat: convert WARN to a pr_info

From: Valdis Kletnieks
Date: Tue Nov 12 2019 - 21:50:57 EST


syzbot took a nosedive because it runs with panic_on_warn set. And
it's quite correct, it shouldn't have been a WARN in the first place.
Other locations just use a pr_info(), so do that here too.
