Rajeev Nandan e8c4aa25c5 disp: msm: dsi: fix bl->raw_bd NULL pointer dereference ...

In trusted vm, a stub function is used for the panel_ops.bl_register,
hence the backlight_device bl->raw_bd used for WLED backlight type
remains uninitialized.

If the panel backlight is WLED, this can cause a NULL pointer
dereference in TVM during dsi_panel_bl_handoff().

Add a check before dereferencing bl->raw_bd.
