video: fbdev: clcdfb: Fix refcount leak in clcdfb_of_vram_setup

BugLink: https://bugs.launchpad.net/bugs/1981864
[ Upstream commit b23789a59fa6f00e98a319291819f91fbba0deb8 ]

of_parse_phandle() returns a node pointer with refcount incremented, we should
use of_node_put() on it when not need anymore.  Add missing of_node_put() to
avoid refcount leak.
