ipv6: fix warning in net/ipv6/ip6_flowlabel.c

this warning: net/ipv6/ip6_flowlabel.c: In function ‘ipv6_flowlabel_opt’: net/ipv6/ip6_flowlabel.c:467: warning: ‘err’ may be used uninitialized in this function triggers because GCC does not recognize the (correct) error flow between fl_create() and 'err'. Annotate it. Signed-off-by: Ingo Molnar <[email protected]> Signed-off-by: David S. Miller <[email protected]>
