staging: unisys: Fix CamelCase for Disk Add/Remove global variables in virthba.c

This patch fixes the Disk Add/Remove (DAR) related CamelCase global
variables in virthba.c, reported by the checkpatch script:
  DARWorkQ --> dar_work_queue
  DARWorkQHead --> dar_work_queue_head
  DARWorkQLock --> dar_work_queue_lock
  DARWorkQSched --> dar_work_queue_sched
