Joerg Roedel 8e998fc24d x86/mm: Sync also unmappings in vmalloc_sync_all() 
With huge-page ioremap areas the unmappings also need to be synced between
all page-tables. Otherwise it can cause data corruption when a region is
unmapped and later re-used.

Make the vmalloc_sync_one() function ready to sync unmappings and make sure
vmalloc_sync_all() iterates over all page-tables even when an unmapped PMD
is found.

Fixes: 5d72b4fba4 ('x86, mm: support huge I/O mapping capability I/F')
