David S. Miller 6c00055a81 tipc: Don't use structure names which easily globally conflict.
Andrew Morton reported a build failure on sparc32, because TIPC
uses names like "struct node" and there is a like named data
structure defined in linux/node.h

This just regexp replaces "struct node*" to "struct tipc_node*"
to avoid this and any future similar problems.
