Antoine Tenart 199d97815d crypto: inside-secure - avoid unmapping DMA memory that was not mapped ...

commit c957f8b3e2 upstream.

This patch adds a parameter in the SafeXcel ahash request structure to
keep track of the number of SG entries mapped. This allows not to call
dma_unmap_sg() when dma_map_sg() wasn't called in the first place. This
also removes a warning when the debugging of the DMA-API is enabled in
the kernel configuration: "DMA-API: device driver tries to free DMA
memory it has not allocated".
