Joerg Roedel d73a6d722a iommu/amd: Fix small race between invalidate_range_end/start 
Commit e79df31 introduced mmu_notifer_count to protect
against parallel mmu_notifier_invalidate_range_start/end
calls. The patch left a small race condition when
invalidate_range_end() races with a new
invalidate_range_start() the empty page-table may be
reverted leading to stale TLB entries in the IOMMU and the
device. Use a spin_lock instead of just an atomic variable
to eliminate the race.
