    aarch64: Fix fma steering when rename fails [PR120119]

    Regrename can fail in some case and `insn_rr[INSN_UID (insn)].op_info`
    will be null. The FMA steering code was not expecting the failure to
happen.
    This started to happen after early RA was added but it has been a latent
bug
    before that.

    Build and tested for aarch64-linux-gnu.
