rcu: Mark interrupts-enabled accesses to rdp->cpu_no_qs.s
The rdp->cpu_no_qs.s field is accessed only by the current CPU,
but can be accessed both at task level and from interrupt handlers.
All accesses from interrupts-enabled code must therefore be marked.
This commit therefore converts from __this_cpu_read() to this_cpu_read(),
but only in interrupts-enabled code, that is, the rcu_qs() function.
KCSAN located this issue.
