pcm: hw: remove superfluous code to call of SNDRV_PCM_IOCTL_SYNC_PTR in snd_pcm_hw_forward()

Browse source 
SNDRV_PCM_IOCTL_SYNC_PTR command was introduced to PCM protocol/interface
in its version 2.0.7, however this command is used in a branch for the
newer version protocol/interface in snd_pcm_hw_forward().

This commit removes the superfluous code as a part of work for code
refactoring.

Fixes: eafb492512 ("- added SYNC_PTR ioctl support for pcm_hw plugin")
