sched: fix profile allocation failure handling

[ upstream commit a042481 ]

This patch fixes return value judgment when allocate memory to store the
subport profile, and releases memory of 'rte_sched_port' if code fails to
apply for this memory.

Fixes: 0ea4c6a ("sched: add subport profile table")
