IB/hfi1: Do not destroy link_wq when the device is shut down
commit 2315ec12ee8e8257bb335654c62e0cae71dc278d upstream.
The workqueue link_wq should only be destroyed when the hfi1 driver is
unloaded, not when the device is shut down.
Fixes: 71d47008ca1b ("IB/hfi1: Create workqueue for link events")
