plugin:dshare: wrong state reporting

Browse source 
If plugin dshare detects underrun, it reports this to the user
via return value -EPIPE and setting dshare state to 'xrun' which is correct.
But, if user after this wants to check the stream state, it is misleadingly
reported as 'running' instead of 'xrun'.
With this behavior aplay e.g. will not do a proper underrun handling
(restarting stream) but terminates streaming.
This is due to plugin dshare always returns state of the slave pcm,
in pcm_ops->state() which is not correct.
