PCI: endpoint: test: Synchronously cancel command handler work

Browse Source 
Use cancel_delayed_work_sync() in pci_epf_test_epc_deinit() to ensure
that the command handler is really stopped before proceeding with DMA
and BAR cleanup.

The same change is also done in pci_epf_test_link_down() to ensure that
the link down handling completes with the command handler fully stopped.
