The helper rte_eth_dma_zone_reserve() is called by PMDs
when probing a new port.
It creates a new memzone with an unique name.
The name of this memzone was using the name of the driver
doing the probe.
In order to avoid assigning the driver before the end of the probing
(next patch), the driver name is removed from these memzone names.
The ethdev name (data->name) is not used because it may be too long
and may be not set at this stage of probing.
Syntax of old name: <driver>_<ring>_<port>_<queue>
Syntax of new name: eth_p<port>_q<queue>_<ring>
