iptables: spurious error in load_extension
In commit 927385017047d (iptables: improve error reporting with extension
loading troubles), a new error message was added in an attempt to handle
the case where a match does not support a particular protocol family.
For instance, attempting to use the osf match on IPv6.
Unfortunately, this error message now triggers when creating a new chain
which has the same name as a match extension, because iptables calls
xtables_find_target with the name of the new chain to verify it does not
clash with an existing target. For example:
# iptables -N tcp
/usr/lib/xtables/libxt_tcp.so: no "tcp" extension found for this protocol
I attempted to resolve this by adding a new XTF flag, but that required changes
in many different places (including -j handling). It seems easiest just to
remove this warning and stick with the original error message of ENOENT, even
if less than precise.
