[PATCH] fill_tgid: cleanup delays accounting
fill_tgid() should skip not only an already exited group leader. If the
task has ->exit_state != 0 it already did exit_notify(), so it also did
fill_tgid_exit()->delayacct_add_tsk(->signal->stats) and we should skip it
to avoid a double accounting.
This patch doesn't close the race completely, but it cleanups the code.
