vfio, spapr: Fix levels calculation
The existing tries to round up the number of pages but @pages is always
calculated as the rounded up value minus one which makes ctz64() always
return 0 and have create.levels always set 1.
This removes wrong "-1" and allows having more than 1 levels. This becomes
handy for >128GB guests with standard 64K pages as this requires blocks
with zone order 9 and the popular limit of CONFIG_FORCE_MAX_ZONEORDER=9
means that only blocks up to order 8 are allowed.
