ASoC: SOF: sof-audio: Skip unprepare for in-use widgets on error rollback

Browse Source 
If the ipc_prepare() callback fails for a module instance, on error rewind
we must skip the ipc_unprepare() call for ones that has positive use count.

The positive use count means that the module instance is in active use, it
cannot be unprepared.

The issue affects capture direction paths with branches (single dai with
multiple PCMs), the affected widgets are in the shared part of the paths.
