MIPS: WARN_ON invalid DMA cache maintenance, not BUG_ON
[ Upstream commit d4da0e97baea8768b3d66ccef3967bebd50dfc3b ]
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.
