Joerg Roedel 46ac18c347 iommu/amd: Check PM_LEVEL_SIZE() condition in locked section 
The increase_address_space() function has to check the PM_LEVEL_SIZE()
condition again under the domain->lock to avoid a false trigger of the
WARN_ON_ONCE() and to avoid that the address space is increase more
often than necessary.
