[PATCH net] nfp: double free on error in probe

[Dan Carpenter]

Both the nfp_net_pf_app_start() and the nfp_net_pci_probe() functions
call nfp_net_pf_app_stop_ctrl(pf) so there is a double free.  The free
should be done from the probe function because it's allocated there so
I have removed the call from nfp_net_pf_app_start().
