fix maxcpus=N parsing
Commit 61ec7567db103d537329b0db9a887db570431ff4 ('ACPI: boot correctly with "nosmp" or "maxcpus=0"') broke 'maxcpus=' handling on x86[-64]. maxcpus=N is now having no effect on x86_64, and freezing bootup on i386 (because of inconsistency with the separate maxcpus parsing down in arch/i386, I guess). That's because early_param parsing is a little different from __setup parsing, and needs the "=" omitted: then it seems to work as the original commit intended (no mention of IO-APIC in /proc/interrupts when maxcpus=0).
