[PATCH v1 2/4] ACPI: OSL: Rearrange workqueue selection in acpi_os_execute()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Replace the 3-branch if () statement used for selecting the target
workqueue in acpi_os_execute() with a switch () one that is more
suitable for this purpose and carry out the work item initialization
before it to avoid code duplication.

No intentional functional impact.
