rcu: Fix missing TICK_DEP_MASK_RCU_EXP dependency check
[ Upstream commit db7b464df9d820186e98a65aa6a10f0d51fbf8ce ]
This commit adds checks for the TICK_DEP_MASK_RCU_EXP bit, thus enabling
RCU expedited grace periods to actually force-enable scheduling-clock
interrupts on holdout CPUs.
Fixes: df1e849ae455 ("rcu: Enable tick for nohz_full CPUs slow to provide expedited QS")
