[PATCH 2/2] drm: bridge: it66121: fix a resource leak in probe

[Dan Carpenter <dan.carpenter@oracle.com>]

In the original code if the "ctx = devm_kzalloc()" allocation failed
then we should have called of_node_put(ep); before returning.  It's
actually a bit easier to do the allocation first before assigning
ep = of_graph_get_endpoint_by_regs().

Fixes: 988156dc2fc9 ("drm: bridge: add it66121 driver")
