Input: serio/gameport - use 'long' system workqueue
Commit 8ee294cd9def0004887da7f44b80563493b0a097 converted serio subsystem event handling from using a dedicated thread to using common workqueue. Unfortunately, this regressed our boot times, due to the fact that serio jobs take long time to execute. While the new concurrency managed workqueue code manages long-playing works just fine and schedules additional workers as needed, such works wreck havoc among remaining users of flush_scheduled_work(). To solve this problem let's move serio/gameport works from system_wq to system_long_wq which nobody tries to flush.
