[PATCH 03/42] ntfs3: Drop pointless sync_mapping_buffers() and invalidate_inode_buffers() calls

[Jan Kara <jack@suse.cz>]

ntfs3 never calls mark_buffer_dirty_inode() and thus its metadata
buffers list is always empty. Drop the pointless sync_mapping_buffers()
and invalidate_inode_buffers() calls.
