RDMA/hfi1: Stop flushing the global IB workqueue

Browse Source 
hfi1 does not queue work on ib_wq. QSFP and link work run on the per-port
link_wq, while the remaining device work uses hfi1_wq or dedicated queues.
The probe failure path destroys both per-port workqueues, and normal device
removal flushes them in shutdown_device() before destroying them.

Remove the flushes of the core-owned global workqueue. Waiting for
unrelated core or other device work is not part of hfi1 teardown.

Fixes: 71d47008ca ("IB/hfi1: Create workqueue for link events")
