Remove incorrect assert about hermetic state. (#88885)
I'm not sure why I thought this assert was valid in the first
place, and there's no comment about it.
The assert is tantamount to saying, "no tensor objects should
become dead via SafePyObject when hermetic mode is on." But
suppose we run a Python GC while we're inside hermetic mode.
This could result in us disposing non-hermetic tensors, which
would hit decref. So the assert seems invalid.
