qapi/expr.py: Check type of union and alternate 'data' member Prior to this commit, specifying a non-object value here causes the QAPI parser to crash in expr.py with a stack trace with (likely) an AttributeError when we attempt to call that value's items() method. This member needs to be an object (Dict), and not anything else. Add a check for this with a nicer error message, and formalize that check with new test cases that exercise that error.
