gpu: nvgpu: add nvgpu_get_v2_user_class()

Browse Source 
Add a function to find the nvgpu_class of the v2 user device nodes. This
is the last entry in the class list, as the devices are created in that
order.

The v2 user class is not defined when MIG is enabled because there are
multiple logical devices; bigger changes would be needed for this.
