Robin Murphy 68bc7b2003 iommu: Avoid more races around device probe 
commit a2e7e59a94269484a83386972ca07c22fd188854 upstream.

It turns out there are more subtle races beyond just the main part of
__iommu_probe_device() itself running in parallel - the dev_iommu_free()
on the way out of an unsuccessful probe can still manage to trip up
concurrent accesses to a device's fwspec. Thus, extend the scope of
iommu_probe_device_lock() to also serialise fwspec creation and initial
retrieval.
