[PATCH] remoteproc: qcom: q6v5-mss: Use common error handling code in q6v5_mpss_load()

[Markus Elfring <Markus.Elfring@xxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 24 Sep 2024 15:55:06 +0200

Add jump targets so that a bit of exception handling can be better reused
at the end of this function implementation.
