net: liquidio: Fix off-by-one error in VF setup_nic_devices() cleanup

Browse source

[ Upstream commit 6cbba46934 ]

In setup_nic_devices(), the initialization loop jumps to the label
setup_nic_dev_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.

Compile tested only. Issue found using code review.
