Existing implementation of reset_resume handler just calls ath6kl_usb_remove() that deallocates all resources. It can lead to double free, etc. on disconnect. The patch removes reset_resume handler, so usb core could conservatively reset the driver. Found by Linux Driver Verification project (linuxtesting.org).
