firmware: arm_scmi: Account for failed debug initialization

Browse source

[ Upstream commit 2290ab43b9 ]

When the SCMI debug subsystem fails to initialize, the related debug root
will be missing, and the underlying descriptor will be NULL.

Handle this fault condition in the SCMI debug helpers that maintain
metrics counters.
