    rs6000: Fix the condition with frame_pointer_needed_indeed [PR96072]

    As PR96072 shows, the code adding REG_CFA_DEF_CFA reg note
    makes one assumption that we have emitted one insn which
    restores the frame pointer previously.  That part of code
    was guarded with flag frame_pointer_needed before, it was
    consistent, but it was replaced with flag
    frame_pointer_needed_indeed since commit r10-7981.  It
    caused ICE due to unexpected NULL insn.

            * config/rs6000/rs6000-logue.c (rs6000_emit_epilogue): Update t=

            frame_pointer_needed_indeed.
