#781: [patch] care about update flag in iwspy data

Keywords: iwspy updated | Patch_attached: 1
-----------------------------------------------+----------------------------
The data returned by an iwspy-get-ioctl (`struct iw_quality`) contains the
field `updated` which informs if the quality data has been updated since
the last iwspy-get-ioctl. This field is currently allways set to true,
even if the quality information has not been updated since last ioctl.
The attached patch sets the field `updated` appropriately.
It works as follows:
The quality data returned by an iwspy-get-ioctl is based on the RSSI value
of the last recevied frame of a node (last-frame-rssi). When reading the
RSSI value, now additionally the last-frame-timestamp of that node is
stored. So if there is again an iwspy-get-ioctl, we can check if a certain
node has an updated RSSI value by comparing the stored and current last-
frame-timestamp of a node.
