[PATCH] examples/ip_reassembly: remove conflicting Tx offload

IP packet reassembly requires the MULTI_SEGS offload to be enabled in order
to handle fragmented packets across multiple memory segments. However, the
MBUF_FAST_FREE offload conflicts with MULTI_SEGS and cannot be enabled
simultaneously.

Remove the MBUF_FAST_FREE offload to avoid conflicts with MULTI_SEGS.
