block: ensure bdi->io_pages is always initialized
commit de1b0ee490eafdf65fac9eef9925391a8369f2dc upstream.
If a driver leaves the limit settings as the defaults, then we don't
initialize bdi->io_pages. This means that file systems may need to
work around bdi->io_pages == 0, which is somewhat messy.
Initialize the default value just like we do for ->ra_pages.
