bnxt_en: Fix possible crash in bnxt_hwrm_ring_free() under error conditions.
If we encounter errors during open and proceed to clean up,
bnxt_hwrm_ring_free() may crash if the rings we try to free have never
been allocated. bnxt_cp_ring_for_rx() or bnxt_cp_ring_for_tx()
may reference pointers that have not been allocated.
Fix it by checking for valid fw_ring_id first before calling
bnxt_cp_ring_for_rx() or bnxt_cp_ring_for_tx().
Fixes: 2c61d2117ecb ("bnxt_en: Add helper functions to get firmware CP ring ID.")
