RTEMS | rtems: A returned partition buffer asserts in the chain append (#5750)

[Sebastian Huber (@sebhub)]

Issue created by Sebastian Huber: https://gitlab.rtems.org/rtems/rtos/rtems/-/work_items/5750



`rtems_partition_get_buffer()` hands the application a buffer which the chain
of free buffers used as a node. The application may write to every byte of it.
`_Partition_Free_buffer()` appends the buffer without a reset of the node. A
debug build therefore ends `rtems_partition_return_buffer()` with a failed
assertion in `_Chain_Append_unprotected()`. The test `regulator01` shows this.

Found while running the test suite with `RTEMS_DEBUG`. This description was
created with Claude Code assistance.
