[PATCH net v3 0/3] net: liquidio: Fix memory leaks in setup_nic_devices()

[Zilin Guan]

This series fixes memory leaks in the initialization paths of the 
NIC devices.

Patch 1 fixes an off-by-one error in the PF cleanup loop. It ensures
the current device index is cleaned up and correctly handles the 
post-loop devlink_alloc failure case.

Patch 2 fixes the same off-by-one error in the VF cleanup loop.

Patch 3 moves the initialization of oct->props[i].netdev before queue 
setup calls. This ensures that if queue setup fails, the cleanup function 
can find and free the allocated netdev. It also initializes lio->oct_dev 
early to prevent a crash in the cleanup path.

Signed-off-by: Zilin Guan <zilin@xxxxxxxxxx>

Changes in v3:
- Split the off-by-one fix into separate patches for PF and VF.
- Patch 1: Decrement i in the devlink_alloc error path before jumping
  to cleanup to avoid accessing an invalid index.
- Patch 3: Initialize lio->oct_dev alongside props->netdev to prevent 
  NULL pointer dereference in cleanup_rx_oom_poll_fn().

Changes in v2:
- Add patch 1 to fix an off-by-one error in the error handling loop logic.
