f16::ZERO and f16::ONE are mixed up

[izveigor]

Describe the bug
DivideByZero occurs when div_checked and mod_checked are called with the argument f16::ONE.

To Reproduce

use half::f16;
use arrow::array::Float16Array;
use arrow::datatypes::ArrowNativeTypeOp;

fn main() {
    let arr: Float16Array = [Some(f16::from_f64(1.0)), Some(f16::from_f64(2.0))].into_iter().collect();
    println!("{:#?}", arr);
    println!("{:#?}", arr.value(0).div_checked(f16::ONE));
    println!("{:#?}", arr.value(0).mod_checked(f16::ONE));
}

output:

PrimitiveArray<Float16>
[
  1.0,
  2.0,
]
Err(
    DivideByZero,
)
Err(
    DivideByZero,
)

Expected behavior
output:

PrimitiveArray<Float16>
[
  1.0,
  2.0,
]
1.0
0.0
