Wang Hai 716cd2eba3 ipv6: addrlabel: fix possible memory leak in ip6addrlbl_net_init 
[ Upstream commit e255e11e66 ]

kmemleak report a memory leak as follows:

unreferenced object 0xffff8880059c6a00 (size 64):
  comm "ip", pid 23696, jiffies 4296590183 (age 1755.384s)
  hex dump (first 32 bytes):
    20 01 00 10 00 00 00 00 00 00 00 00 00 00 00 00   ...............
    1c 00 00 00 00 00 00 00 00 00 00 00 07 00 00 00  ................

    [<0000000099df30e7>] entry_SYSCALL_64_after_hwframe+0x44/0xa9

We should free all rules when we catch an error in ip6addrlbl_net_init().
otherwise a memory leak will occur.
