usb: uas: set host status byte on data completion error
[ Upstream commit 9d32685a251a754f1823d287df233716aa23bcb9 ]
Set the host status byte when a data completion error is encountered
otherwise the upper layer may end up using the invalid zero'ed data.
The following output was observed from scsi/sd.c prior to this fix.
[ 11.872824] sd 0:0:0:1: [sdf] tag#9 data cmplt err -75 uas-tag 1 inflight:
