Ashish Srivastava 7c2b4d70ec gpu: nvgpu: gv11b: fix get ptr update for mmu fault buffer ...

Skipping the last entry makes get ptr 0.
This causes HW to think that buffer overflow has happened,
but it really hasn't. Due to this issue no further progress
is possible as all FB entries beyond get ptr are invalid.
