net/bnxt: handle ring cleanup in case of error

[ upstream commit 75915b2 ]

In bnxt_alloc_mem(), after bnxt_alloc_async_ring_struct(),
any of the functions failure causes an error:

bnxt_hwrm_ring_free(): hwrm_ring_free nq failed. rc:1

Fix this by initializing ring->fw_ring_id to INVALID_HW_RING_ID
in bnxt_alloc_async_ring_struct().

Fixes: bd0a14c ("net/bnxt: use dedicated CPR for async events")
