ALSA: pcm: fix fifo_size frame calculation

commit a9960e6a293e6fc3ed414643bb4e4106272e4d0a upstream.

The calculated frame size was wrong because snd_pcm_format_physical_width()
actually returns the number of bits, not bytes.

Use snd_pcm_format_size() instead, which not only returns bytes, but also
simplifies the calculation.

Fixes: 8bea869c5e56 ("ALSA: PCM midlevel: improve fifo_size handling")
