Fabio M. De Francesco 377a80ca65 ALSA: pcm: Test for "silence" field in struct "pcm_format_data" 
commit 2f7a26abb8241a0208c68d22815aa247c5ddacab upstream.

Syzbot reports "KASAN: null-ptr-deref Write in
snd_pcm_format_set_silence".[1]

It is due to missing validation of the "silence" field of struct
"pcm_format_data" in "pcm_formats" array.

Add a test for valid "pat" and, if it is not so, return -EINVAL.
