of: resolver: Add of_node_put() before return and break

mainline inclusion
from mainline-v5.3-rc5
commit 60d437bb
category: bugfix
bugzilla: 20547, https://gitee.com/openeuler/kernel/issues/I6H9U5
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=60d437bbff358748fcfc3bce5f08da9a6b3761da



--------------------------------

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