This commit fixes an use after free introduced in Commit e55a4acb54 (" efi_loader: net: set EFI bootdevice device path to HTTP when loaded from wget"). The logic in efi_net_set_dp is reworked so that when the function is invoked it not only changes the value of the static variable net_dp (this is how the function was implemented in e55a4acb54) but also updates the protocol interface of the device path protocol in case efi has started.
