Wang Hai fa6882c636 tipc: fix memory leak in tipc_topsrv_start()
kmemleak report a memory leak as follows:

unreferenced object 0xffff88810a596800 (size 512):
  comm "ip", pid 21558, jiffies 4297568990 (age 112.120s)
  hex dump (first 32 bytes):

'srv' is malloced in tipc_topsrv_start() but not free before
leaving from the error handling cases. We need to free it.
