sched/fair: Remove unused variable from expire_cfs_rq_runtime()

Commit 78becc2709 ("sched: Use an accessor to read the rq clock")
introduces rq_clock(), which obsoletes the use of the "rq" variable
in expire_cfs_rq_runtime() and triggers this build warning:

  kernel/sched/fair.c: In function 'expire_cfs_rq_runtime':
  kernel/sched/fair.c:2159:13: warning: unused variable 'rq' [-Wunused-variable]
