Chenghao Duan bb85d206be samples/ftrace: Adjust LoongArch register restore order in direct calls
Ensure that in the ftrace direct call logic, the CPU register state
(with ra = parent return address) is restored to the correct state after
the execution of the custom trampoline function and before returning to
the traced function. Additionally, guarantee the correctness of the jump
logic for jr t0 (traced function address).
