Added lookup for pool name because secondary process should attach to
mempool created by primary process rather than create new one.
Added function free_shared_dev_data() used at the exit of the testpmd.
This causes detach devices data from array rte_eth_dev_data[] shared
between all processes. This allows to have a up-to-date list of devices
data and run again secondary application with the same name.
