drivers/net: enable device detach on secondary process

Browse Source 
With the enabling for hotplug on multi-process,
rte_eth_dev_pci_generic_remove can be used to detach the device from
a secondary process also. But we need to take care of the uninit callback
parameter to make sure it handles the secondary case correctly.
