intel-iommu: Check for an RMRR which ends before it starts.
commit 5595b528b49a702c0428c0762bab60999648254c upstream.
Some HP BIOSes report an RMRR region (a region which needs a 1:1 mapping
in the IOMMU for a given device) which has an end address lower than its
start address. Detect that and warn, rather than triggering the
BUG() in dma_pte_clear_range().
