acpi: Don't use MAX_CPUMASK_BITS for APIC ID bitmap
MAX_CPUMASK_BITS is a limit for max_cpus and CPU indexes, not for APIC IDs. ACPI_CPU_HOTPLUG_ID_LIMIT is the right macro for the limit on APIC IDs on the ACPI and CPU hotplug code. There are no functional changes introduced by this patch, as MAX_CPUMASK_BITS + 1 == 255 + 1 == 256 == ACPI_CPU_HOTPLUG_ID_LIMIT.
