On debug builds, this re-attached the\nthread state under the mutex and then called PyErr_Occurred() with the\nthread state detached in the chunking loop of `_hacl_hmac_state_update()`.\n\nReturn the raw HACL* exit code instead and convert it in `_hmac.new()` and\n`_hmac.HMAC.update()` once the thread state is re-attached and the mutex\nis released, as `hmac_digest_compute_locked()` already does. Release\nbuilds keep ignoring the update() exit code.\n\nSince `_hacl_convert_errno()` is now always called with an attached\nthread state, remove the `PyGILState_Ensure()` added by gh-135561 and\nassert that a thread state is attached instead.\n\n* simplify ifdefs: always check for the hacl error\n\n---------\n\nCo-authored-by: Gregory P.
