Without this fix, hovering the mouse over a nan pixel in an imshow()
would result in Warning: converting a masked element to nan. and then
ValueError: cannot convert float NaN to integer. Fix that.

The format_cursor_data test doesn't explicitly check the return value
of get_cursor_data anymore because np.ma.masked is returned for nan
inputs (this is expected from the general approach for handling invalid
data); checking that format_cursor_data gives the right string is
sufficient.

Regression coming from #20949.
