wiphy: Remove unneeded variable

Browse Source 
Instead of always mallocing space for the ssid array, and then freeing
it in most circumstances, do the opposite.  Only allocate the array once
it is actually needed.  This has the side effect of removing an unneeded
variable and making the code simpler.
