gpu: nvgpu: Remove dead priv_cmdbuf code

Remove the gp_get and gp_put pointers from the priv_cmdbuf code. These
pointers appear to track the position of th the priv_cmdbuf in the gp_fifo.
However, these pointers are not used for anything nor are they needed for
anything in the future. This code appears to be a relic left over from the
past.
