Ying Xue 5492390a94 tipc: simplify relationship between name table lock and node lock 
When tipc name sequence is published, name table lock is released
before name sequence buffer is delivered to remote nodes through its
underlying unicast links. However, when name sequence is withdrawn,
the name table lock is held until the transmission of the removal
message of name sequence is finished. During the process, node lock
is nested in name table lock. To prevent node lock from being nested
in name table lock, while withdrawing name, we should adopt the same
locking policy of publishing name sequence: name table lock should
be released before message is sent.
