[media] radio-wl1273: Fix two warnings

drivers/media/radio/radio-wl1273.c: In function ‘wl1273_fm_upload_firmware_patch’:
drivers/media/radio/radio-wl1273.c:675:2: warning: ‘n’ may be used uninitialized in this function
drivers/media/radio/radio-wl1273.c:675:2: warning: ‘i’ may be used uninitialized in this function

Those vars are never initialized, and the debug message makes no sense, as it
will show just two random values.
