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:
[   11.872826] sd 0:0:0:1: [sdf] tag#9 CDB: Read capacity(16) 9e 10 00 00 00 00 00 00 00 00 00 00 00 20 00 00
[   11.872830] sd 0:0:0:1: [sdf] Sector size 0 reported, assuming 512.
