raid5: fix broken async operation chain

ops_run_reconstruct6() doesn't correctly chain asyn operations. The tx returned
by async_gen_syndrome should be added as the dependent tx of next stripe.

The issue is introduced by commit 59fc630b8b5f9f21c8ce3ba153341c107dce1b0c
    RAID5: batch adjacent full stripe write
