DataClass: Passing List member as argument to function fails

[ubaidsk]

Example:

(lp) lpython$ cat examples/expr2.py 
from lpython import i32, dataclass

@dataclass
class A:
    x: list[i32]

def f(b: list[i32]):
    print(b)

def main0():
    a: A = A([1, 2, 3])
    f(a.x)

main0()
(lp) lpython$ python examples/expr2.py 
[1, 2, 3]
(lp) lpython$ lpython examples/expr2.py
