gpu: nvgpu: vgpu: init vars in gk20a vgpu missed

Browse Source 
pending_sema_waits and a few other variables in struct gk20a is used
in gk20a shutdown path but we didn't initialize them in vgpu. I added
a function vgpu_init_vars dedicated to init variables for struct gk20a.
The native code also similar function nvgpu_init_vars().

This is a quick fix. Finally, the common probe code is better be put
in common function btween vgpu and native gpu.
