ebtables: Fix for broken chain renaming
Loading extensions pollutes 'errno' value, hence before using it to indicate failure it should be sanitized. This was done by the called function before the parsing/netlink split and not migrated by accident. Move it into calling code to clarify the connection. Fixes: a7f1e208cdf9c ("nft: split parsing from netlink commands") Signed-off-by: Phil Sutter <>
