intel-iommu: update root_scalable before switching as during post_load
We need check whether passthrough is enabled during
vtd_switch_address_space() by checking the context entries. This
requires the root_scalable to be set correctly otherwise we may try to
check legacy rsvd bits instead of scalable ones.
Fixing this by updating root_scalable before switching the address
spaces during post_load.
Fixes: fb43cf739e ("intel_iommu: scalable mode emulation")
