[PATCH master f15-branch NTH?] Check repo instead of method type when enabling network in loader (#673824)

[Radek Vykydal <rvykydal@xxxxxxxxxx>]

Now when we have stage 2 in initrd.img.

This change fixes netinstall which is not identified as METHOD_CDROM
because of missing .treeinfo/.discinfo so initial METHOD_URL is kept.

I wonder if this this check is also worth fixing, or if we even should
add .treeinfo to netinst.iso.
