s390/ftrace: use la instead of aghik in return_to_handler()
Nathan Chancellor reported the following build error when compiling the kernel with CONFIG_MARCH_Z10=y: arch/s390/kernel/mcount.S: Assembler messages: arch/s390/kernel/mcount.S:140: Error: Unrecognized opcode: `aghik' The aghik instruction is only available since z196. Use the la instruction instead which is available for all machines.
