LoongArch: BPF: Adjust the parameter of emit_jirl()

The branch instructions beq, bne, blt, bge, bltu, bgeu and jirl belong
to the format reg2i16, but the sequence of oprand is different for the
instruction jirl. So adjust the parameter order of emit_jirl() to make
it more readable correspond with the Instruction Set Architecture manual.

Here are the instruction formats:

  beq     rj, rd, offs16
  bne     rj, rd, offs16
  blt     rj, rd, offs16
  bge     rj, rd, offs16
  bltu    rj, rd, offs16
  bgeu    rj, rd, offs16
  jirl    rd, rj, offs16
