[PATCH] net: netfilter: fix GCC uninitialized warning

[Dmitry Safonov]

With x86_64_defconfig:
GCC thinks that in nfulnl_recv_config flags parameter is not inited but
it was under the same condition (nfula[NFULA_CFG_FLAGS] == true).
Suppress this warning:
	net/netfilter/nfnetlink_log.c: In function ânfulnl_recv_configâ:
	net/netfilter/nfnetlink_log.c:320:14: warning: âflagsâ may be used uninitialized in this function [-Wmaybe-uninitialized]
  	inst->flags = flags;
	            ^
