When we suspend, we can't really remember our BSS table.
Purge all the data.
Export this function to allow driver to purge the BSS table
in case they feel the need to.
iwlwifi will need to do that.

This is obviously out of place and we already have an implementation
for this upstream.  Johannes dropped it.  Sorry for the trouble. :(
