Jon Hunter e914561b6e gpu: nvgpu: Fix crash on reboot 
A kernel panic has been observed sometimes on reboot. The crash occurs
in the nvgpu_kernel_shutdown_notification() function when calling
nvgpu_cond_signal(). Fix this by checking that the 'gr' pointer is valid
before calling nvgpu_cond_signal().
