MDEV-28480: Assertion `0' failed in Item_row::illegal_method_call on

Browse Source 
SELECT FROM JSON_TABLE

Analysis: When fix_fields_if_needed() is called, it doesnt check if operands
are valid because check_cols() is not called. So it doesn't error out and
eventually crashes.
Fix: Use fix_fields_if_needed_for_scalar() instead of
fix_fields_if_needed(). It filters the scalar and returns the error if
it occurs.
