Remove asserts that confuse enum _framestate with enum _frameowner

The owner field of _PyInterpreterFrame is supposed to be a member of
enum _frameowner, but FRAME_CLEARED is a member of enum _framestate.
At present, it happens that FRAME_CLEARED is not numerically equal to
any member of enum _frameowner, but that could change in the future.
The code that incorrectly assigned owner = FRAME_CLEARED was deleted
in commit a53cc3f (pythonGH-116687).
Remove the incorrect checks for owner != FRAME_CLEARED as well.
