netfilter: xtables: change xt_match.checkentry return type
Restore function signatures from bool to int so that we can report
memory allocation failures or similar using -ENOMEM rather than
always having to pass -EINVAL back.
This semantic patch may not be too precise (checking for functions
that use xt_mtchk_param rather than functions referenced by
xt_match.checkentry), but reviewed, it produced the intended result.
// <smpl>

type bool;
identifier check, par;

-bool check
+int check
(struct xt_mtchk_param *par) { ... }
