ALSA: pcmtest: Reject invalid fill_mode values
The fill_block() function handles only fill_mode 0 (random) and 1
(pattern). With any other value it writes nothing and does not move the
buffer position. A capture stream then gets no data, and a read fails
with -EIO after the timeout. Nothing in the kernel log says why.
Check the value in a set callback, so a bad value is rejected both when
the module is loaded and when the parameter is written.
