soc: qcom: pmic_glink_altmode: fix port sanity check

Browse source

commit c4fb7d2eac upstream.

The PMIC GLINK altmode driver currently supports at most two ports.

Fix the incomplete port sanity check on notifications to avoid
accessing and corrupting memory beyond the port array if we ever get a
notification for an unsupported port.
