  mathematics: remove asserts from av_rescale_rnd()

Conflicts:
	libavutil/mathematics.c

The asserts are left in place for now as no code checks the return
value, but we sure can change this if application developers
prefer

The table is so small that the space gain is not worth the
performance overhead of cross-library access.
