virnet*: Don't unlock object in dispose

As of bba93d40 all of our RPC objects are derived from
virObjectLockable. However, during rewrite some errors sneaked
in. For instance, the dispose functions to virNetClient and
virNetServerClient objects were not only freeing allocated
memory, but unlocking themselves. This is wrong. Object should
never disappear while locked.
