I am running this set on x1e. During tests with fluster I often see
error code 0x04000008

[  103.787979] qcom-iris aa00000.video-codec: session error received
0x4000008: unknown

Seems worthwhile to add this one, and maybe other missing error codes
as well, here and to iris_hfi_gen2_handle_session_error() below.
