x86: cpumask: update 32-bit APM not to mug current->cpus_allowed
Impact: cleanup, avoid cpumask games
The APM code wants to run on CPU 0: we create an "on_cpu0" wrapper
which uses work_on_cpu() if we're not already on cpu 0.
This introduces a new failure mode: -ENOMEM, so we add an explicit
err arg and handle Linux-style errnos in apm_err().
