acpi: Use apic_id_limit when calculating legacy ACPI table size
The code that calculates the legacy ACPI table size for migration
compatibility uses max_cpus when calculating legacy_aml_len (the size of
the DSDT and SSDT tables). However, the SSDT grows according to APIC ID
limit, not max_cpus.
The bug is not triggered very often because of the 4k alignment on the
table size. But it can be triggered if you are unlucky enough to cross a
4k boundary.
Change the legacy_aml_len calculation to use apic_id_limit, to calculate
the right size.
