Jason Yan d9a434fa0c scsi: core: Fix warning in scsi_alloc_sgtables()
As explained in SG_IO howto[1]:

"If iovec_count is non-zero then 'dxfer_len' should be equal to the sum of
iov_len lengths. If not, the minimum of the two is the transfer length."

When iovec_count is non-zero and dxfer_len is zero, the sg_io() just
genarated a null bio, and finally caused a warning below. To fix it, skip
generating a bio for this request if dxfer_len is zero.
