ASoC: Intel: avs: Clean up the bus when fetching ML caps fails
snd_hdac_ext_bus_get_ml_capabilities() may fail and its return code
shall be checked and accounted for. Address the issue by updating the
error-path for avs_pci_probe().
At the same time, if the function in question succeeds but the next part
of avs_pci_probe() fails, the hlink list shall be cleaned up before
leaving the scope.
Fixes: 1affc44ea5dd ("ASoC: Intel: avs: PCI driver implementation")
