[PATCH 03/11] ASoC: SOF: amd: fix amd_sof_acp_probe() error unwind ordering

[Vijendar Mukunda]

Call amd_sof_sdw_exit() after free_irq() in the free_ipc_irq error
label of amd_sof_acp_probe(). Without this, an IRQ that fires between
sdw context teardown and free_irq() can dereference freed SoundWire
resources.
