drm/i915/hdcp: check streams[] bounds before overflow
The data->streams[] overflow check is done after the buffer overflow has
already happened. Move the overflow check before the write.
Side note, emitting a warning splat with a backtrace might be overkill
here, but prefer not changing the behaviour other than not doing the
overrun.
Discovered using AI-assisted static analysis confirmed by Intel Product
Security.
