tipc: use lock_sock() in tipc_sk_reinit()
lock_sock() must be used in process context to be race-free with
other lock_sock() callers, for example, tipc_release(). Otherwise
using the spinlock directly can't serialize a parallel tipc_release().
As it is blocking, we have to hold the sock refcnt before
rhashtable_walk_stop() and release it after rhashtable_walk_start().
Fixes: 07f6c4bc048a ("tipc: convert tipc reference table to use generic rhashtable")
