MFC r296615: Make ZFS ignore stripe sizes above SPA_MAXASHIFT (8KB).
If device has stripe size bigger then maximal sector size supported by
ZFS, there is nothing can be done to avoid read-modify-write cycles.
Taking that stripe size into account will only reduce space efficiency
and pointlessly bother user with warnings that can not be fixed.
