iommu/amd: Fix amd_iommu_free_device() put_device_state_wait() doesn't loop on the condition and a spurious wakeup will have it free the device state even though there might still be references out to it. Fix this by using 'normal' wait primitives. Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Joerg Roedel <jroedel@suse.de>
