ASoC: SOF: Fix runtime pm usage counter balance after fw exception
If the retain context is enabled we will unconditionally increment the
device's pm use count on each exception and when the drivers are unloaded
we do not correct this (as we don't know how many times we 'prevented
d3 entry').
Introduce a flag to make sure that we do not increment the use count more
than once and on module unload decrement the use count if needed to
balance it.
