[PATCH] ASoC: soc-pcm: use GFP_ATOMIC in dpcm_create_debugfs_state()

[Christophe JAILLET]

The commit below states that dpcm_be_connect() may be called from atomic
context. It changes a GFP_KERNEL into a GFP_ATOMIC to deal with it.

Another memory allocation is done in dpcm_create_debugfs_state() which is
called by dpcm_be_connect(). Also use GFP_ATOMIC there to be consistent
and be compliant with atomic context.

Not clear to me how dpcm_be_connect() can be called from an atomic context,
though. But better safe than sorry.
