  All hardware drivers should allocate IOVA-contiguous
memzones for their hardware resources.

This fixes the following drivers in one go:

grep -Rl rte_eth_dma_zone_reserve drivers/

drivers/net/avf/avf_rxtx.c
drivers/net/thunderx/nicvf_ethdev.c
drivers/net/e1000/igb_rxtx.c
drivers/net/e1000/em_rxtx.c
drivers/net/fm10k/fm10k_ethdev.c
drivers/net/vmxnet3/vmxnet3_rxtx.c
drivers/net/liquidio/lio_rxtx.c
drivers/net/i40e/i40e_rxtx.c
drivers/net/sfc/sfc.c
drivers/net/ixgbe/ixgbe_rxtx.c
drivers/net/nfp/nfp_net.c

Notes:
    v4: replaced use of new API with additional memzone flag
    
    v3: moved this patch earlier in the patchset
