net/ena: fix freeing memory using correct API

Memory zones should be freed using the proper memzone_free function not
rte_free which is for malloc calls.
After allocating memzone it's required to zeroize memory in it, so do so
before storing the handle for later freeing.

Fixes: 9ba7981ec992 ("ena: add communication layer for DPDK")
