ASoC: Intel: avs: Unprepare a stream when XRUN occurs

Browse Source 
The pcm->prepare() function may be called multiple times in a row by the
userspace, as mentioned in the documentation. The driver shall take that
into account and prevent redundancy. However, the exact same function is
called during XRUNs and in such case, the particular stream shall be
reset and setup anew.
