parport_pc: make sure to release IO ports after probing for IT87XX
Commit f63fd7e299ee13da071ecfce2b90b58c5e1562b1 ("parport_pc: detection
for SuperIO IT87XX POST") only released the IO port region on success,
not when the probe for the IT87XX chip failed.
That caused not only a reserved region to leak, but also caused an oops
when the driver module was unloaded and somebody tried to cat
/proc/ioports - because the string that was assigned to the IO port
region was a static string in the module virtual address area.
