ntfs_non_resident_attr_shrink() shrinks attribute sizes but fails to
trim the page cache. This leaves orphaned dirty folios beyond the new
end of the attribute, leading to writeback failures (-ENOENT), data
loss, and $EA chain corruption.
Fix this by truncating the page cache to the new size immediately after
updating the sizes, preventing writeback from flushing out-of-range folios.
