Alex Hung eb5556c208 drm/amd/display: Check index msg_id before read or write 
[ Upstream commit 59d99deb330af206a4541db0c4da8f73880fba03 ]

[WHAT]
msg_id is used as an array index and it cannot be a negative value, and
therefore cannot be equal to MOD_HDCP_MESSAGE_ID_INVALID (-1).

[HOW]
Check whether msg_id is valid before reading and setting.

This fixes 4 OVERRUN issues reported by Coverity.
