Input: serio - fix blocking of parport



[ Upstream commit 1a5e251996e1b602f2ddc9261ee9de0ca1875bfa ]

If parkbd_allocate_serio() fails to allocate memory we are releasing the
parport but we missed unregistering the device. As a result this device
with exclusive access to that parport remains registered. And no other
device will be able to use that parport even though this driver has
failed to load.
