net/smc: wake up wr_reg_wait when terminating a link group
If a new connection with a new rmb is added to a link group, its
memory region is registered. If a link group is terminated, a pending
registration requires a wake up.
And consolidate setting of tx_flag peer_conn_abort in smc_lgr_terminate().
