add conditional to check ndim

[antareepsarkar]

Description

It checks the value of ndim when the argument for data is an np.ndarray in pandas.array(data, dtype=None, copy=True)

Reason

import pandas as pd
a = pd.array(np.array([[1], [2]]))

Raises an error because the array is 2-D

import pandas as pd
a = pd.array(np.array([[1], ['a']]))

Does not raise an error in this case(maybe, because the value is now a string). But, it should raise an error as only 1-D arrays can be passed as arguments.
