tipc: modify socket iterator for sock_diag
The current socket iterator function tipc_nl_sk_dump, handles socket locks and calls __tipc_nl_add_sk for each socket. To reuse this logic in sock_diag implementation, we do minor modifications to make these functions generic as described below. In this commit, we add a two new functions __tipc_nl_sk_walk, __tipc_nl_add_sk_info and modify tipc_nl_sk_dump, __tipc_nl_add_sk accordingly. In __tipc_nl_sk_walk we: 1. acquire and release socket locks 2. for each socket, execute the specified callback function In __tipc_nl_add_sk we: - Move the netlink attribute insertion to __tipc_nl_add_sk_info. tipc_nl_sk_dump calls tipc_nl_sk_walk with __tipc_nl_add_sk as argument. sock_diag will use these generic functions in a later commit. There is no functional change in this commit.
