[PATCH] example/ip_pipeline: fix source port mempool assignment

[Fan Zhang <roy.fan.zhang@intel.com>]

Fixes the wrong source port mempool assignment (commit id eb32fe7c). The
source port is now assigned by parsed mempool id index value either by
default or configured by CFG file.

Previously, the mempool id for locating source port's mempool pointer was
the port id. When multiple source ports exist in the same pipeline, and
the default mempool configuration is used (one MEMPOOL0 is shared between
all source ports), the invalid mempool pointer (NULL) will be assigned to
source ports other than first source port.
