hp_accel: do not call ACPI from invalid context

The LED on HP notebooks is connected through ACPI.  That unfortunately
means that it needs to be delayed by using schedule_work() to avoid
calling the ACPI interpreter from an invalid context.

[akpm@linux-foundation.org: use flush_work() rather than sort-of reimplementing it]
