ixgbe: destroy aci.lock later within ixgbe_remove path

ixgbe: destroy aci.lock later within ixgbe_remove path

There's another issue with aci.lock and previous patch uncovers it.
aci.lock is being destroyed during removing ixgbe while some of the
ixgbe closing routines are still ongoing. These routines use Admin
Command Interface which require taking aci.lock which has been already
destroyed what leads to call trace.

Same as for the previous commit, the issue has been highlighted by the
commit 337369f8ce9e ("locking/mutex: Add MUTEX_WARN_ON() into fast path").

Move destroying aci.lock to the end of ixgbe_remove(), as this
simply fixes the issue.
