hash: fix TSX aborts with newer gcc

gcc 7 and 8 with O3 will generate vzeroupper from rte_memcpy
into TSX region which may abort the TSX transaction.

This fix changes rte_memcpy to memcpy which will not insert
extra vzeroupper into the library.

Fixes: f2e3001b53ec ("hash: support read/write concurrency")
