[PATCH 12/18] staging: crystalhd: call disable_pci_device() if pci_probe() failed

[Kulikov Vasiliy]

Driver should call disable_pci_device() if it returns from pci_probe()
with error. Also it must not be called if pci_request_region() fails as
it means that somebody uses device resources and rules the device.
