ALSA: pcm: Allow dropping stream directly after resume

Browse source

So far, the PCM core refuses DROP ioctl when the stream in the
suspended state.  This was basically to avoid the invalid state change
*during* the suspend.  But since we protect the power change globally
in the common PCM ioctl caller side, it's guaranteed that
snd_pcm_drop() is called at the right power state.  So we can assume
that the drop of stream is safe immediately after SUSPENDED state.
