Subject: [PATCH net] net: sched: fix initialiser warning in sch_frag.c

Debian gcc 10.2.1 complains thusly:

net/sched/sch_frag.c:93:10: warning: missing braces around initializer [-Wmissing-braces]
   struct rtable sch_frag_rt = { 0 };
          ^
net/sched/sch_frag.c:93:10: warning: (near initialization for 'sch_frag_rt.dst') [-Wmissing-braces]

Fix it by removing the unnecessary '0' initialiser, leaving the
braces.

Fixes: 31fe34a0118e ("net/sched: sch_frag: fix stack OOB read while fragmenting IPv4 packets")
