gpu: nvgpu: bvec for struct nvgpu_tsg_sm_error_state fields

Browse Source 
Add Setter and Getter methods for accessing tsg->sm_error_states.
Getter returns a constant pointer for struct nvgpu_tsg_sm_error_state.
This renders it unnecessary to add BVEC for above fields for the struct
in multiple locations. The current design ensures that only a constant
pointer is obtained from the owner unit i.e. FIFO.

The following new methods are added. Both unit tests and BVEC tests
are added for them as well.

nvgpu_tsg_store_sm_error_state
nvgpu_tsg_get_sm_error_state
