netfilter: arpt_mangle: fix return values of checkentry
In 135367b "netfilter: xtables: change xt_target.checkentry return type", the type returned by checkentry was changed from boolean to int, but the return values where not adjusted. arptables: Input/output error This broke arptables with the mangle target since it returns true under success, which is interpreted by xtables as >0, thus returning EIO.
