Ivan Malov e7a1d51009 xsk: Clear page contiguity bit when unmapping pool 
[ Upstream commit 512d1999b8 ]

When a XSK pool gets mapped, xp_check_dma_contiguity() adds bit 0x1
to pages' DMA addresses that go in ascending order and at 4K stride.

The problem is that the bit does not get cleared before doing unmap.
As a result, a lot of warnings from iommu_dma_unmap_page() are seen
in dmesg, which indicates that lookups by iommu_iova_to_phys() fail.

Fixes: 2b43470add ("xsk: Introduce AF_XDP buffer allocation API")
