ALSA: pcm: Protect delay DMA sync in forward and rewind, too
Like the previous fix for snd_pcm_delay() (in the commit 50f413b83b31
"ALSA: pcm: Protect delay DMA sync against concurrent HW_FREE"), the
snd_pcm_dma_buffer_sync() call in snd_pcm_forward() and
snd_pcm_rewind() needs the similar protection against the concurrent
hw_free action for avoiding potential UAFs.
