[PATCH v3] sched: remove useless malloc in pie data init

[Weiguo Li <liwg06@foxmail.com>]

'rte_pie_rt_data_init(NULL)' is not expected, and it's ought to
fail when this happen. The malloc inside the function didn't work.
So remove the malloc otherwise will lead to a memory leak.

Fixes: 44c730b0e37971 ("sched: add PIE based congestion management")
