LoopToMap Parallelizing Loops That Should Not Become Maps

LoopToMap parallelizes this loop taken from the tsvc 2 benchmark:

```
@dace.program
def dace_s2244(a: dace.float64[LEN_1D],
b: dace.float64[LEN_1D],
c: dace.float64[LEN_1D],
e: dace.float64[LEN_1D]):

for nl in range(ITERATIONS):
for i in range(LEN_1D - 1):
a[i + 1] = b[i] + e[i]
a[i] = b[i] + c[i]
```

I have attached the SDFG as a JSON.
