Always review suggested coccinelle patches before submission and
see if there are ways to improve the code beyond what the spatch
tool suggests.

Perhaps integrate these tests and removed an indent level too:

	if (find_p2p_ie && !find_p2p_ps_ie &&
	    p2pinfo->p2p_ps_mode > P2P_PS_NONE)
		rtl_p2p_ps_cmd(hw, P2P_PS_DISABLE);
