The vt6656 is prone to resetting on the usb bus.
It seems there is a race condition and wpa supplicant is
trying to open the device via iw_handlers before its actually
closed at a stage that the buffers are being removed.
The device is longer considered open when the
buffers are being removed. So move ~DEVICE_FLAGS_OPENED
flag to before freeing the device buffers.

Preliminary to removing compare_ether_addr altogether:
Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.
Additionally:
Used is_zero_ether_addr, removed now unused variable
Converted uses of &foo[0] to foo
Done via cocci script: (and a little typing)
