[PATCH] i2c-i801.c: don't pci_disable_device() after it was just enabled

Commit 02dd7ae2892e5ceff111d032769c78d3377df970 ("[PATCH] i2c-i801:
Merge setup function") has a missing return 0 in the _probe() function.
This means the error path is always executed and pci_disable_device() is
called even when the device just got successfully enabled.

Having the SMBus device disabled makes some systems (eg.
Fujitsu-Siemens Lifebook E8010) hang hard during power-off.

Intead of reverting the whole commit this patch fixes it up:
- don't ever call pci_disable_device(), also not in the _remove() function
  to avoid hangs
- fix missing pci_release_region() in error path
