netif_running() returns true before rtl_open(): issuing rtl_reset_work()
synchronously against uninitialized rings right at the start of rtl_open()
won't work as expected.
pm_runtime_get_sync() could be issued later in rtl_open() (but I would
not mind something different with runtime_{resume/suspend} in open/close).
