scsi: sg: fix SG_DXFER_FROM_DEV transfers
commit 68c59fcea1f2c6a54c62aa896cc623c1b5bc9b47 upstream.
SG_DXFER_FROM_DEV transfers do not necessarily have a dxferp as we set
it to NULL for the old sg_io read/write interface, but must have a
length bigger than 0. This fixes a regression introduced by commit
28676d869bbb ("scsi: sg: check for valid direction before starting the
request")
