    bpf: fix zero_extendqidi2 ldx template
    
    Commit 77d0f9ec3809b4d2e32c36069b6b9239d301c030 inadvertently changed
    the normal asm dialect instruction template for zero_extendqidi2 from
    ldxb to ldxh. Fix that.
    
    gcc/
    
            * config/bpf/bpf.md (zero_extendqidi2): Correct asm template to
            use ldxb instead of ldxh.
