[PATCH -tip] sched/fair: Remove unused variable from expire_cfs_rq_runtime()

[Kamalesh Babulal <kamalesh@linux.vnet.ibm.com>]

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

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