[PATCH] Introduce sg_set_buf

sg_init_one is a nice tool for the block layer.  However, users
of struct scatterlist in other subsystems don't usually need the
DMA attributes.  For them it's a waste of time and space to
initialise the whole struct scatterlist structure.

Therefore this patch adds a new function sg_set_buf to initialise
a scatterlist without zeroing the DMA attributes.
