[PATCH v1 2/3] remoteproc: qcom: q6v5: Do not report crash if SSR is disabled

[Gokul krishna Krishnakumar]

In case recovery is disabled, do not report the rproc crash
to the framework. If recovery is enabled after we start the
crash handler we may end up in a weird state by informing
clients of a crash twice, resulting in undefined behaviour.
