scsi: sg: Don't use GFP_ATOMIC in sg_start_req()
sg_start_req() is called from normal user context and can sleep when
waiting for memory. Switch it to use GFP_KERNEL, which fixes allocation
failures seen with the bio_alloc rework.
Fixes: b520c4eef83d ("block: split bio_alloc_bioset more clearly into a fast and slowpath")
