[PATCH v2 05/18] PCI: endpoint: test: Synchronously cancel command handler work

[Damien Le Moal <dlemoal@kernel.org>]

Replace the call to cancel_delayed_work() with a call to
cancel_delayed_work_sync() in pci_epf_test_unbind(). This ensures that
the command handler is really stopped when proceeding with dma and bar
cleanup.
