tipc: missing entries in name table of publications

Browse Source 
When binding multiple services with specific type 1Ki, 2Ki..,
this leads to some entries in the name table of publications
missing when listed out via 'tipc name show'.

The problem is at identify zero last_type conditional provided
via netlink. The first is initial 'type' when starting name table
dummping. The second is continuously with zero type (node state
service type). Then, lookup function failure to finding node state
service type in next iteration.

To solve this, adding more conditional to marked as dirty type and
lookup correct service type for the next iteration instead of select
the first service as initial 'type' zero.
