CVE-2026-23257

In the Linux kernel, the following vulnerability has been resolved:

net: liquidio: Fix off-by-one error in PF setupnicdevices() cleanup

In setupnicdevices(), the initialization loop jumps to the label setupnicdev_free on failure. The current cleanup loop while(i--) skip the failing index i, causing a memory leak.

Fix this by changing the loop to iterate from the current index i down to 0.

Also, decrement i in the devlink_alloc failure path to point to the last successfully allocated index.

Compile tested only. Issue found using code review.
