block: fix error handling in sg_io
Before commit 2cada584b200 ("block: cleanup error handling in sg_io"),
we had ret = 0 before entering the last big if block of sg_io.
Since 2cada584b200, ret = -EFAULT, which breaks hdparm:
/dev/sda:
setting Advanced Power Management level to 0xc8 (200)
HDIO_DRIVE_CMD failed: Bad address
APM_level = 128
