ublk: check for ublk_unmap_io() returning 0
If the userspace ublk server passes an unmapped address as the data
buffer for a completed ublk read, ublk_unmap_io() will return 0
indicating no bytes could be copied. Currently, this will result in
calling blk_update_request() with nr_bytes=0, which doesn't seem
supported. Fail the I/O with BLK_STS_IOERR in this case instead.
