efi_loader: completely initialize network

Browse source 
Add missing network initialization code.

Before the patch the network was only usable if a network command like
dhcp or tftp had beed executed.

This was visible when interrupting the console countdown and executing
bootefi selftest for vexpress_ca15_tc2_defconfig.
