Nicolin Chen 52305f0514 gpu: nvgpu: Reduce structure padding waste ...

The gk20a_init_fifo_setup_sw_common() function allocates memory of
schannel_gk20a and tsg_gk20a tructures for all 512 channels:
    Size   Caller                    Module  Pages     Type
    749568 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=182 vmalloc
    602112 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=146 vmalloc

This change just simply reorgnizes the member defines in those two
structures to reduce padding waste. After this change:
    Size   Caller                    Module  Pages     Type
    733184 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=178 vmalloc
    585728 __nvgpu_vzalloc+0x28/0x78 [nvgpu] pages=142 vmalloc

In summary, it saves 8 pages in 32KB memory.
