PMD .remove function just call rte_dma_pmd_release() and it's will
invoke PMD .dev_close ops:
rte_dma_pmd_release()
--> rte_dma_close()
--> PMD .dev_close ops
PMD could implemente cleanup in dev_close ops.
If the PMD want support multi-process, just make sure only the primary
could do really cleanup in the dev_close ops.
