soundwire: intel: Fix uninitialized adev deref

[ Upstream commit e1c815f4b24a305e5bc9eceb541674bf4d02b709 ]

In case of error, we can dereference uninitialized 'adev'

drivers/soundwire/intel_init.c:154 sdw_intel_acpi_cb()
error: uninitialized symbol 'adev'.

Fix that by not using adev for warn print and make it pr_err.
