mac80211: move sdata debugfs dir to vif
There is need create driver own per interface debugfs files. This is currently done by drv_{add,remove}_interface_debugfs() callbacks. But it is possible that after we remove interface from the driver (i.e. on suspend) we call drv_remove_interface_debugfs() function. Fixing this problem will require to add call drv_{add,remove}_interface_debugfs() anytime we create and remove interface in mac80211. So it's better to add debugfs dir dentry to vif structure to allow to create/remove custom debugfs driver files on drv_{add,remove}_interface().
