PCI: Don't read past the end of sysfs "driver_override" buffer



When printing the driver_override parameter when it is 4095 and 4094 bytes
long, the printing code would access invalid memory because we need count+1
bytes for printing.

Fixes: 782a985d ("PCI: Introduce new device binding path using pci_dev.driver_override")
