rcu: Remove redundant call to rcu_boost_kthread_setaffinity()

Browse source

The rcu_boost_kthread_setaffinity() function is invoked at
rcutree_online_cpu() and rcutree_offline_cpu() time, early in the online
timeline and late in the offline timeline, respectively.  It is also
invoked from rcutree_dead_cpu(), however, in the absence of userspace
manipulations (for which userspace must take responsibility), this call
is redundant with that from rcutree_offline_cpu().  This redundancy can
be demonstrated by printing out the relevant cpumasks

This commit therefore removes the call to rcu_boost_kthread_setaffinity()
from rcutree_dead_cpu().
