Correct the test on RNG device presence,when ret is equal to 0, before to call dm_rng_read function.

Without this patch the RNG device is not used when present (when ret == 0) or a data abort occurs in dm_rng_read when CONFIG_DM_RNG is activated but the RNG device is not present in device tree (ret != 0 and devp = NULL).
