[patch] incorrectly detected roaming with WPA...

[Peter Jones <pjones redhat com>]

I was at my brother's house for part of last week, and he's using WPA in
a location where there are a lot of APs visible, all on different
networks (i.e. suburbia).  Occasionally NM would try to associate to the
wrong AP, and it'd log a message about roaming between two APs.  When I
look up the addresses, they've got unique ESSIDs.  So here's a patch to
prohibit it.  I'm pretty sure it's not the *best* answer, but it does
allow it to connect correctly.
