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.
The following Linux kernels are affected:
* 2.6.35.9
* 2.6.36.4
* 2.6.37.3
