sparc: vio: use put_device() instead of kfree()

BugLink: http://bugs.launchpad.net/bugs/1783418
[ Upstream commit 00ad691ab140b54ab9f5de5e74cb994f552e8124 ]

Never directly free @dev after calling device_register(), even
if it returned an error. Always use put_device() to give up the
reference initialized.
