[#1441] ir: Do not validate subnet removal

Browse source 
It is useless process since subnet owner is able to delete subnet without an
Alphabet approval. The Alphabet should only validate netmap state after
removal:
1. Update nodes' attributes if they were included in the deleted subnet;
2. Remove nodes without any subnet entrance.
