ASoC: dpcm: fix BE dai not hw_free and shutdown
In case, one BE is used by two FE1/FE2
FE1--->BE-->
|
FE2----]
when FE1/FE2 call dpcm_be_dai_hw_free() together
the BE users will be 2 (> 1), hence cannot be hw_free
the be state will leave at, ex. SND_SOC_DPCM_STATE_STOP
later FE1/FE2 call dpcm_be_dai_shutdown(),
will be skip due to wrong state.
leaving the BE not being hw_free and shutdown.
The BE dai will be hw_free later when calling
dpcm_be_dai_shutdown() if still in invalid state.
