P2P: Remove unreachable code in wpas_p2p_stop_find()

Commit 152cff6ba6d6ac206b93a2202eab57f0a36c26cb ('P2P: Remove
WPA_DRIVER_FLAGS_P2P_MGMT option') removed the only non-zero return from
wpas_p2p_stop_find_oper(), but did not remove the useless return value
or the return check in wpas_p2p_stop_find(). Clean these up by removing
unreachable code and useless return value.
