sysfs: convert BUG_ON to WARN_ON
It's rude to crash the system just because the developer did something
wrong, as it prevents them from usually even seeing what went wrong.
So convert the few BUG_ON() calls that have snuck into the sysfs code
over the years to WARN_ON() to make it more "friendly". All of these
are able to be recovered from, so it makes no sense to crash.
