ntfs3: add setlease file operation

Add the setlease file_operation to ntfs_file_operations,
ntfs_legacy_file_operations, ntfs_dir_operations, and
ntfs_legacy_dir_operations, pointing to generic_setlease.  A future
patch will change the default behavior to reject lease attempts with
-EINVAL when there is no setlease file operation defined. Add
generic_setlease to retain the ability to set leases on this
filesystem.
