bdrv_commit() could return 0 or 1 on success, depending on whether or
not the last sector was allocated in the overlay and whether the overlay
format had a .bdrv_make_empty callback.
Most callers ignored it, but qemu-img commit would print an error
message while the operation actually succeeded.
Also clean up the handling of I/O errors to return the real error code
instead of -EIO.
