ALSA: pcm: Simplify params_period_bytes()
The hw_params struct has a parameter that contains the period size in bytes. This can be used instead of deriving the value from other parameters. This is similar to e.g. params_buffer_bytes() Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
