What this PR does / why we need it:
Fix hung in remote lock if cn restart quickly, it will call remote lock on rpc io goroutine, and block all remote requests.
Assuming that we have cn0, cn1, and table1, we consider the following timing:
the bind t1-cn0-table1-version1 valid
sends a lock request to cn0.
this lock-table bind to be a remote lock table, because the serviceID(t1-cn0) != serviceID(t2-cn0). This
will make rpc handle blocked.
