Fix a memory leak with scsi-mq triggered by commands with large data
transfer length.
__sg_alloc_table() sets both table->nents and table->orig_nents to the
same value. When the scatterlist is DMA-mapped, table->nents is
overwritten with the (possibly smaller) size of the DMA-mapped
scatterlist,

Thanks Tony,
this looks good to me. In the long run I'll see how we can hide
these implementation details in the lib/scatterlist.c code instead
of burdening it on the users.
