[LTP] [PATCH v2 3/3] dio_sparse: Fix child exit code

[Martin Doucha <mdoucha@suse.cz>]

dio_sparse currently ignores all child failures because children never
exit with non-zero code. Fix child exit status.

Signed-off-by: Martin Doucha <mdoucha@suse.cz>

Changes since v1:
- Use tst_res(TFAIL)+exit(1) instead of tst_brk()
