ftrace/x86: Have save_mcount_regs store RIP in %rdi for first parameter Instead of having save_mcount_regs store the RIP in %rdx as a temp register to place it in the proper location of the pt_regs on the stack. Use the %rdi register as the temp register. This lets us remove the extra store in the ftrace_caller_setup macro.
