Staging: wlan-ng: silence a sparse warning

Browse Source 
This doesn't change the behavior.  It just silences a sparse warning.

drivers/staging/wlan-ng/hfa384x_usb.c:2810:62: warning: dubious: !x | !y

The point of the bitwise OR is so that a logical OR could short circuit
the second call to test_and_set_bit().
