d1497977fecb9acce05988d6322ad415ef93bb39 upstream.
sg_dma_len() macro can be used only on scattelists which are mapped, so
all calls to it before dma_map_sg() are invalid. Replace them by proper
check for direct sg segment length read.

Fixes:

[bwh: Backported to 3.2: unaligned DMA is unsupported so there is a different
set of calls to replace]
