mac80211: add a HW flag for supporting HW TX fragmentation
Currently mac80211 determines whether HW does fragmentation by checking whether the set_frag_threshold callback is set or not. However, some drivers may want to set the HW fragmentation capability depending on HW generation. Allow this by checking a HW flag instead of checking the callback.
