Paul Burton 0d1d365d1d MIPS: WARN_ON invalid DMA cache maintenance, not BUG_ON ...

[ Upstream commit d4da0e97ba ]

If a driver causes DMA cache maintenance with a zero length then we
currently BUG and kill the kernel. As this is a scenario that we may
well be able to recover from, WARN & return in the condition instead.
