Small cleanup patch for net/tipc/name_distr.c::tipc_named_node_up()
Patch does the following:
- Change a few pointer assignments from 0 to NULL (makes sparse happy).
- Move a few variable assignment outside the tipc_nametbl_lock lock.
- Make sure to free the allocated buffer before returning so we don't leak.
Note: patch is compile tested only and I'm not familiar with this code, so
please check my changes carefully.
