rocker: Create an ordered workqueue for FIB offload
As explained in the previous commits, we need to process FIB entries
addition / deletion events in FIFO order or otherwise we can have a
mismatch between the kernel's FIB table and the device's.
Create an ordered workqueue for rocker to which these work items will be
submitted to.
