Wang Hai ab19e393e8 tipc: fix memory leak in tipc_topsrv_start() 
[ Upstream commit fa6882c63621821f73cc806f291208e1c6ea6187 ]

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):
    00 00 00 00 ad 4e ad de ff ff ff ff 00 00 00 00  .....N..........
    ff ff ff ff ff ff ff ff 00 83 60 b0 ff ff ff ff  ..........`.....

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