netfilter: xt_NFLOG: don't call nf_log_packet in NFLOG module.

This patch modifies xt_NFLOG to suppress the call to nf_log_packet()
function. The call of this wrapper in xt_NFLOG was causing NFLOG to
use the first initialized module. Thus, if ipt_ULOG is loaded before
nfnetlink_log all NFLOG rules are treated as plain LOG rules.
