Deepak Nibade ae2f9da28e gpu: nvgpu: fix channel close sequence ...

In gk20a_cde_remove_ctx(), current sequence is as below
- gk20a_channel_close()
- gk20a_deinit_cde_img()
  - gk20a_free_obj_ctx()

But gk20a_free_obj_ctx() needs reference to channel and hence
below crash is seen :

[ 3901.466223] Unable to handle kernel paging request at virtual address
00001624
...
[ 3901.535218] PC is at gk20a_free_obj_ctx+0x14/0xb0
[ 3901.539910] LR is at gk20a_deinit_cde_img+0xd8/0x12c

Fix this by closing the channel after gk20a_deinit_cde_img()
