ACPI: OSL: Clean up the removal of unused memory mappings

Fold acpi_os_map_cleanup_deferred() into acpi_os_map_remove() and pass the latter to INIT_RCU_WORK() in acpi_os_drop_map_ref() to make the code more straightforward. No intentional functional impact. Signed-off-by: Rafael J. Wysocki <[email protected]>
