Subject: [PATCH 2/3] scripts/gdb: timerlist: fix rb_node access

"strcut timerqueue_head" no longer has "next" member since v5.4-rc1:
commit 511885d7061e ("lib/timerqueue: Rely on rbtree semantics for next
timer")

Therefore, access "rb_node" through active->rb_root->rb_root->rb_node.

Moreoever, remove  curr.address.cast() on rb_node as this breaks the code
and is not necessary.
