Nicolas Benech 6c5f67792c gpu: nvgpu: vm: remove unreachable code ...

There are 2 instances where some code is unreachable in vm.c
- The nvgpu_insert_mapped_buf function always returned 0, so any
  associated error handling was unreachable. This patch changes
  the function to return void instead.
- A cleanup section to unmap a buffer in case of error was also
  unreachable.
