drm/amd/display: Bounds-check connector->index in dm_dp_mst_get_modes
dm_dp_mst_get_modes() uses drm_connector->index to index the
per-connector HDCP arrays in struct hdcp_workqueue. Those arrays are
sized to AMDGPU_DM_MAX_DISPLAY_COUNT, which matches the DRM connector
index range (0..31). Add a defensive bounds check so that, should the
DRM connector index range ever grow beyond the array size, the access
is skipped instead of reading and writing out of bounds.
