[patch 17/28] watchdog: Fix probe function of riowd

[Thomas Gleixner]

After sucessfully registering the misc device the driver iounmaps the
device registers and kfree's the device data structure. Ouch !

This was introduced with commit e42311d75 (riowatchdog: Convert to
pure OF driver) and went unnoticed for more than a year :)

Return success instead of dropping into the error cleanup code path.
