kernel/delayacct.c: remove redundant checking in __delayacct_add_tsk()
The wrapper function delayacct_add_tsk() already checked 'tsk->delays',
and __delayacct_add_tsk() has no another direct callers, so can remove the
redundancy checking code.
And the label 'done' is also useless, so remove it, too.
