1. No matter what the mbuf size is, the data buffer size should not
be greater than 16K - 128.
2. Replace RTE_ALIGN with RTE_ALIGN_FLOOR according to [1].

This patch does two fixes.
1. No matter what the mbuf size is, the data buffer size should not
be greater than 16K - 128.
2. Align data buffer size to 128.
