Subject: [PATCH] drivers: staging: ft1000: ft1000-usb: initialize 'status'
 with STATUS_SUCCESS in request_code_segment()

If "!bool_case", it returns unexpected value instead of STATUS_SUCCESS,
so need fix it, the related warning (with allmodconfig under hexagon):

    CC [M]  drivers/staging/ft1000/ft1000-usb/ft1000_download.o
  drivers/staging/ft1000/ft1000-usb/ft1000_download.c: In function 'request_code_segment':
  drivers/staging/ft1000/ft1000-usb/ft1000_download.c:581:6: warning: 'status' may be used uninitialized in this function [-Wuninitialized]
