[3.11] GH-93516: Drop broken assert, fixes GH-93769

[tiran]

The assert is broken on big endian platforms and not present in the
main branch. Drop it.

Correct version would be _PyOpcode_Deopt[_Py_OPCODE(...)] instead of
_PyOpcode_Deopt[...].

• Issue: Severe performance degradation for tracing under 3.11 #93516
