[PATCH 6.19 757/844] parisc: kernel: replace kfree() with put_device() in create_tree_node()

[Sasha Levin]

From: Haoxiang Li <lihaoxiang@xxxxxxxxxxxxxxxx>

[ Upstream commit dcf69599c47f29ce0a99117eb3f9ddcd2c4e78b6 ]

If device_register() fails, put_device() is the correct way to
drop the device reference.

Found by code review.
