Konsta Holtta f22df728de gpu: nvgpu: free global ctx bufs only if allocated ...

Try to free only allocated buffers in
gr_gk20a_free_global_ctx_buffers(), otherwise the destroy function
pointer would be NULL and crash for nonallocated buffers. This can
happen when init fails for some of the buffers. Additionally, make the
pointer NULL when a buffer is destroyed, to signify this state.

Also refactor the function upwards and call it from
gr_gk20a_alloc_global_ctx_buffers() to reduce code duplication.
