fgraph: Add declaration of "struct fgraph_ret_regs"
In final testing of:
https://patchwork.kernel.org/project/linux-trace-kernel/patch/1fc502712c981e0e6742185ba242992170ac9da8.1680954589.git.pengdonglin@sangfor.com.cn/
"function_graph: Support recording and printing the return value of function"
The test failed due to a new warning found in the build:
kernel/trace/fgraph.c:243:56: warning: ‘struct fgraph_ret_regs’ declared inside parameter list will not be visible outside of this definition or declaration
Instead of asking to send another patch series, just add it and then apply
the updates.
