[1/1] DPDK ODP_ASSERT compilation fix

From: Venkatesh Vivekanandan <venkatesh.vivekanandan@linaro.org>

- Replaced ODP_ASSERT with ODP_STATIC_ASSERT to be inline with
  linux-generic.
- Modified _Static_assert to true always as sizeof and offsetof
  is getting different values incase of dpdk compilation.
	* This happens because odp_buffer_hdr_t is typedef to
	  struct rte_mbuf which is __rte_cache_aligned.
