memory: pl353-smc: Fix refcount leak bug in pl353_smc_probe()
[ Upstream commit 61b3c876c1cbdb1efd1f52a1f348580e6e14efb6 ]
The break of for_each_available_child_of_node() needs a
corresponding of_node_put() when the reference 'child' is not
used anymore. Here we do not need to call of_node_put() in
fail path as '!match' means no break.
While the of_platform_device_create() will created a new
reference by 'child' but it has considered the refcounting.
