ALSA: pcm_dmaengine: Don't synchronize DMA channel when DMA is paused
commit 88e98af9f4b5b0d60c1fe7f7f2701b5467691e75 upstream.
When suspended, the DMA channel may enter PAUSE state if dmaengine_pause()
is supported by DMA.
At this state, dmaengine_synchronize() should not be called, otherwise
the DMA channel can't be resumed successfully.
