Michael Brown 68734b9a4d [efi] Bind to only the topmost instance of the SNP or NII protocols 
UEFI has the mildly annoying habit of installing copies of the
EFI_SIMPLE_NETWORK_PROTOCOL instance on the IPv4 and IPv6 child device
handles.  This can cause iPXE's SNP driver to attempt to bind to a
copy of the EFI_SIMPLE_NETWORK_PROTOCOL that iPXE itself provided on a
different handle.

Fix by refusing to bind to an SNP (or NII) handle if there exists
another instance of the same protocol further up the device path (on
the basis that we always want to bind to the highest possible device).
