- Set ENOMEM error if GPU mapping fails in nvgpu_gr_ctx_alloc(). - In nvgpu_gr_ctx_free_patch_ctx(), it is not possible to have a valid patch buffer without GPU virtual address space. Hence instead of checking for gpu_va, use nvgpu_mem_is_valid() to check if GPU mappings can be removed. - Check if RTV circular buffer is ready within DGPU config. nvgpu_gr_global_ctx_buffer_map() already checks if buffer is ready or not and returns error if buffer is not ready. - g->ops.gr.ctxsw_prog.init_ctxsw_hdr_data() will always be set for each chip. Remove unnecessary NULL check.
