mempool: remove a redundant word in comment
mempool: remove a redundant word in comment

There is a redundant repetition word "for" in comment line of the
file rte_mempool.h after the definition of RTE_MEMPOOL_OPS_NAMESIZE.
The word "for" appears twice in line 359 and 360. One of them is
redundant, so delete it.

Fixes: 449c49b93a6b ("mempool: support handler operations")
