Lakshmanan M 450aa3f0be gpu: nvgpu: corner case failure handling in CE infra interface 
This CL covers the following simple modification,
1) Linux kernel list implementation doesn't handle NULL pointer dereference
   at list_del() api.
2) NULL validation before access the command buffer related operations.
   This required for prevent the illegal/NULL memory access during
   gk20a_ce_create_context_with_cb() failure case.
