V4L/DVB (6020): cx88: Fix use of uninitialized variable

An error message for PCI resource allocation failure used the board type
before it was set.  Just get rid of the error message, as get_ressources()
[sic] already prints one.  Format that error message better, and add the pci
function and subsystem information to better associate the error with what
caused it.
