Added lookup for pool name because secondary process should attach to
mempool created by primary process rather than create new.
Added function free_mp_shared_dev_data() which causes that if secondary
process quit or force quit then detach own devices from common array
rte_eth_dev_data[] for all processes. This allows to have a up-to-date
list of devices and run again secondary application with the same name.
