This patch fixes a kernel panic that can occur when unplugging the HWA dongle while a downstream device is in the process of disconnecting. This involved 2 changes. First, call usb_lock_device_for_reset before usb_reset_device to synchronize the HWA's post_rest and disconnect routines. Second, set the hwarc->neep_urb and hwarc->rd_buffer to NULL when they are freed in the error path in the post_reset routine. This prevents a double free when the disconnect routine is called and attempts to free those resources again.
