sched: remove useless malloc in PIE data init

'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.

sched: add PIE based congestion management

Implement PIE based congestion management based on rfc8033.

The Proportional Integral Controller Enhanced (PIE) algorithm works
by proactively dropping packets randomly.
PIE is implemented as more advanced queue management is required to
address the bufferbloat problem and provide desirable quality of
service to users.

Tests for PIE code added to test application.
Added PIE related information to documentation.
