zebra: Stop leaking labels when receiving nexthops from kernel

This leak is happening:
Direct leak of 96 byte(s) in 2 object(s) allocated from:
    0 0x7f6922eb83b7 in __interceptor_calloc ../../../../src/libsanitizer/asan/asan_malloc_linux.cpp:77

    13 0x7f692250c249 in __libc_start_call_main ../sysdeps/nptl/libc_start_call_main.h:58

Just check to see if it has been allocated.  The nexthop is a stack
variable so it's a bit odd.
