[PATCH] netfilter: xt_hashlimit: fix inconsistent return type in hashlimit_mt_*

[Miaoqian Lin <linmq006@gmail.com>]

The hashlimit_mt_v1() and hashlimit_mt_v2() functions return the
cfg_copy() error code (-EINVAL) instead of false when configuration
copying fails. Since these functions are declared to return bool,
-EINVAL is interpreted as true, which is misleading.

Fixes: 11d5f15723c9 ("netfilter: xt_hashlimit: Create revision 2 to support higher pps rates")
Fixes: bea74641e378 ("netfilter: xt_hashlimit: add rate match mode")
