remoteproc: qcom: q6v5: Avoid handling handover twice

Browse source

[ Upstream commit 54898664e1 ]

A remoteproc could theoretically signal handover twice. This is unexpected
and would break the reference counting for the handover resources (power
domains, clocks, regulators, etc), so add a check to prevent that from
happening.
