tipc: rename fields in struct tipc_link
We rename some fields in struct tipc_link, in order to give them more
descriptive names:
next_in_no -> rcv_nxt
next_out_no-> snd_nxt
fsm_msg_cnt-> silent_intv_cnt
cont_intv -> keepalive_intv
last_retransmitted -> last_retransm
There are no functional changes in this commit.
