rcu: Make TASKS_TRACE_RCU select IRQ_WORK 

mainline inclusion
from mainline-v5.12-rc1
commit c26165ef
category: bugfix
bugzilla: https://e.gitee.com/open_euler/issues/list?issue=I4SV19
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c26165efac41bce0c7764262b21f5897e771f34f



-------------------------------------------------------------------------
