David Brownell af9379c712 documentation: when to BUG(), and when to not BUG() ...

Provide some basic advice about when to use BUG()/BUG_ON(): never, unless
there's really no better option.

This matches my understanding of the standard policy ...  which seems not
to be written down so far, outside of LKML messages that I haven't
bookmarked.
