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.
