memory: pl353: Fix error return code in pl353_smc_probe()
[ Upstream commit 76e5624f3f9343a621dd3f4006f4e4d9c3f91e33 ]
When no child nodes are matched, an appropriate error code -ENODEV should
be returned. However, we currently do not explicitly assign this error
code to 'err'. As a result, 0 was incorrectly returned.
