media: tw5864: Simplify 'tw5864_finidev()'

Browse source 
Some resources are allocated with 'pci_request_regions()', so use
'pci_release_regions()' to free them, instead of a verbose
'release_mem_region()'.

There is no point in calling 'devm_kfree()'. The corresponding resource is
managed, so it will be fried automatically.
