In callgraphs from below kernel APIs, position of application pointer on
PCM buffer is changes, according to given parameters.

  - snd_pcm_lib_read()
  - snd_pcm_lib_readv()
  - snd_pcm_lib_write()
  - snd_pcm_lib_writev()

This operation corresponds to application of new position to runtime of
PCM substream and callback of driver's implementation for
'struct snd_pcm_ops.ack'.

In a former commit, a new local function is added, 'apply_appl_ptr'. The
above code block can be replaced with this function.

This commit replaces the code block with call of the function. The function
is renamed to be shared by several objects.

Queued now, but will be likely declined later due to the rewrites of
the code.

Due to your recent work under reviewing?
