Subject: [PATCH 04/23] xarray: Switch xa_store_range() to use xas_store_noinit()

There is only a single user of xa_store_range() and that is
mm/memremap.c which does not use marks at all. Just switch
xa_store_range() to use xas_store_noinit() to avoid implicit (and
unnecessary for all users) initialization of xarray marks.
