pandas.replace with value numpy.nan causes recursion error on 1.5.1

[timc]

This appears related to #45725 which is marked closed but this is highly reproducible on 1.5.1, Python 3.8.2

import pandas
import numpy

data = list(numpy.nan for b in range(0,100))
df = pandas.DataFrame({'a': data})
df['a'].replace(numpy.nan, None)

Gives error

Confirmed this works as expected on 1.4.4

[asishm]

the fix will be available in 1.5.2 when released.
