x86: fix dma_mapping_error for 32bit x86 Devices like b44 ethernet can't dma from addresses above 1GB. The driver handles this cases by falling back to GFP_DMA allocation. But for detecting the problem it needs to get an indication from dma_mapping_error. The bug is triggered by using a VMSPLIT option of 2G/2G.
