[PATCH] ASoC: Intel: Atom: Fix message handling during drop stream

[Harsha Priya <harshapriya.n@intel.com>]

If a stream is being dropped, the period_elapsed received then after
need not be processed. Processing of the period_elapsed message causes
a time out in drop stream response processing. This patch adds a condition
to skip period_elapsed message processing if the stream is in INIT state.
