* If an interrupt occurs during the fpga_probe routine, the driver can crash due to an uninitalized PCI drvdata field. This change moves the allocation of the PCI drvdata to the prologue of the fpga_probe() routine and then relies upon drvdata->id to determine initialization readiness during the intrpt_handelr() routine.
