Remove the compatibility workaround for older firmware that excluded
COMMAND_RSU_UPDATE and COMMAND_RSU_STATUS from the no-support callback.
This exclusion caused receive_cb to never be invoked for these commands
when firmware returned an unsupported response, leaving callers blocked
until their completion timeout.

Always invoke receive_cb with SVC_STATUS_NO_SUPPORT when the secure
firmware does not recognise a command, regardless of command type.
