block: fix bogus EFAULT error from SG_IO ioctl
Whenever blk_fill_sghdr_rq fails, its errno code is ignored and changed to
EFAULT. This can cause very confusing errors:
$ sg_persist -k /dev/sda
persistent reservation in: pass through os error: Bad address
The fix is trivial, just propagate the return value from
blk_fill_sghdr_rq.
