Bart Van Assche 11eeee00c9 scsi: sg: Do not sleep in atomic context 
commit 90449f2d1e upstream.

sg_finish_rem_req() calls blk_rq_unmap_user(). The latter function may
sleep. Hence, call sg_finish_rem_req() with interrupts enabled instead
of disabled.

Reported-by: syzbot+c01f8e6e73f20459912e@syzkaller.appspotmail.com
Closes: https://lore.kernel.org/linux-scsi/691560c4.a70a0220.3124cb.001a.GAE@google.com/
