Bug in lbs_set_essid

[Jon Nettleton]

I was tracking down a scanning delay that was happening during resume
on my olpc XO 1.5, and came across this bug.  Note, during suspend the
card is completely powered down, so resume is a clean start with no
history.

The card is powered up and initializes a full scan.  Channels 1-4 are
scanned and then an association request for any is initiated.  When
lbs_set_essid is called the SSID is set to garbage, so then the driver
tries to connect to this bogus SSID for a while until it gives up and
then finishes scanning the rest of the channels.

Here is the Association Request with the broken SSID

I haven't written a patch to fix it yet.
