ALSA: bebob: code rafactoring for callback functions to PCM interface
The pairs of pcm.hw_params callback functions and .hw_free callback functions for both direction have no differences. This commit unifies the pairs. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
