tests: Fix p2p_channel_random_social_with_op_class_change cleanup

p2p_oper_reg_class and p2p_oper_channel need to be restored to 0, not an
arbitrary 2.4 GHz channel to avoid issues for following test cases. For
example, p2p_channel_random_social_with_op_class_change followed by
p2p_autogo_pref_chan_not_in_regulatory ended up with the latter test
case failing.
