This patch fixes the following sparse warning:
drivers/staging/vt6655/ioctl.c:44:12: warning: symbol 'wpa_Result'
was not declared. Should it be static?
There is no sense to set up all fields of wpa_Result to zero when
interface set up (in device_open()), because wpa_Result is used
only in code for ioctl 0xff and first lines of this ioctl do the
same work. So this patch deletes part of unneeded code
(initialization of wpa_Result to zero in device_open()) and
declares wpa_Reslult as static to avoid sparse warning.
