iplink: bond_slave: fix ad_actor/partner_oper_port_state output

It seems that I've made a mistake when I exported these, instead of a
space in the end I've put a newline character which is wrong and breaks
the single line output.

Fixes: 7d6bc3b8 ("bonding: export 3ad actor and partner port state")
