There's no need to zero the buffer, as if the routine gets an error,
rc will be different than one.
That fixes the following warning:
/devel/v4l/ktest-build/drivers/media/tuners/tda9887.c: In function
'tda9887_status':
/devel/v4l/ktest-build/drivers/media/tuners/tda9887.c:539:2: warning:
value computed is not used [-Wunused-value]
While here, fix the coding style on this function.
