IB/hfi1: Insure freeze_work work_struct is canceled on shutdown
[ Upstream commit 6d517353c70bb0818b691ca003afdcb5ee5ea44e ]
By code inspection, the freeze_work is never canceled.
Fix by adding a cancel_work_sync in the shutdown path to insure it is no
longer running.
Fixes: 7724105686e7 ("IB/hfi1: add driver files")
