ath9k: Use HW HT capabilites properly
The commit "ath9k: Remove aggregation flags" changed how nodes were being initialized. Use the HW HT cap bits to initialize/de-initialize nodes, else we would be accessing an uninitialized entry during a suspend/resume cycle, resulting in a panic. Reported-by: Justin P.
