We clamp down ram_size to match the sclp increment size. We do
not do the same for maxram_size, which means for large guests
with some sizes (e.g. -m 50000) maxram_size differs from ram_size.
This can break other code (e.g. CMMA migration) which uses maxram_size
to calculate the number of pages and then throws some errors.
