    loader: unload command should reset tg_kernel_supported in gfx_state
    
    While loading kernel, we check if vt/vbe backend support is included in
    kernel and set the tg_kernel_supported flag in gfx_state. unload
    command needs to reset this flag to allow next load to perform
    this check with new kernel.
