[PATCH] wireless: fix mode checking in for_each_interface

[jpt.7196 at gmail.com]

From: Jean-Pierre Tosoni <jp.tosoni at acksys.fr>

When searching through wifi-ifaces for specific modes, the mode string
must be compared as a full word.

Else, adding a future new mode like "newap" or "apdetector" which embed
an existing "ap" mode string, will end in detecting the wrong interface.

This was found while trying to create a new detection service for WIDS.
