Subject: [PATCH] rpmsg: qcom_smd: Fix returning 0 if irq_of_parse_and_map() fails

irq_of_parse_and_map() returns 0 on failure, so this should not be
passed further as error return code.

Fixes: 1a358d350664 ("rpmsg: qcom_smd: Fix irq_of_parse_and_map() return value")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
