net/ice: fix DCF memory leaks

V2-changes:
- Addressed Bruce Richardson's review comments.
- Patch-1: use rte_intr_callback_unregister_sync() in the new error path.
- Patch-5: fix the re-commit leak by swapping the saved config under the lock the VF reset replay holds.

This patch series fixes memory leaks, and related error path issues, in the ice DCF driver.

1. The VF VSI map leaked on DCF hardware init failure, and a failed VLAN capability query left the interrupt callback registered.

2. A failed DCF parent adapter init leaked the dummy main VSI, and a failed flow init also leaked the DDP parser and flow engine state.

3. The queue config message leaked when the required RXDID was not supported.

4. The temporary QoS bandwidth buffers still leaked on every successful hierarchy commit.

5. The QoS bandwidth config saved for replay leaked on every commit, close and reset.

6. TM nodes and shaper profiles leaked on close when the hierarchy was never committed.

7. The representor info leaked when the DCF port was closed.

8. A failed probe left the DCF port and its representors behind. A representor type other than VF is now rejected before the DCF port is created.
