[PATCH] gpu: drm: pl111: pl111_vexpress.c: Add of_node_put() before return

[Nishka Dasgupta]

Each iteration of for_each_available_child_of_node puts the previous
node, but in the case of a break from the middle of the loop there is
no put, thus causing a memory leak. Hence add an of_node_put before the
break.
Issue found with Coccinelle.
