[NETFILTER]: fix forgotten module release in xt_CONNMARK and xt_CONNSECMARK
Fix forgotten module release in xt_CONNMARK and xt_CONNSECMARK
When xt_CONNMARK is used outside the mangle table and the user specified
"--restore-mark", the connmark_tg_check() function will (correctly)
error out, but (incorrectly) forgets to release the L3 conntrack module.
Same for xt_CONNSECMARK.
Fix is to move the call to acquire the L3 module after the basic
constraint checks.
