ALSA: pcm: Handle XRUN at trigger START

When the driver returns -EPIPE for indicating an XRUN already at PCM
trigger START, we should treat properly and set it to the XRUN state.
Otherwise the state is missing and the application would try to issue
trigger again without knowing that it's in an error state.

This is just for a theoretical bug, and it won't happen in most
cases.
