[ Upstream commit e01ce676aaef3b13d02343d7e70f9637d93a3367 ]
The kfree() should be called when of_irq_get_byname() fails or
devm_request_threaded_irq() fails in qcom_add_sysmon_subdev(),
otherwise there will be a memory leak, so add kfree() to fix it.
Fixes: 027045a6e2b7 ("remoteproc: qcom: Add shutdown-ack irq")
