Use RTE_MAX_ETHPORTS instead of rte_eth_dev_count_total()
when allocating eth Rx adapter's per-eth device data structure
to account for hotplugged devices.

eth Rx adapter has been updated to support hotplugged
devices, devices created after adapter creation can now be
added to the adapter.

Update the adapter_multi_eth_add_del
test case to create the adapter as part of test setup
instead of creating it after creating vdevs.
