Use cmdq_pkt_create() and cmdq_pkt_destroy() common function
instead of implementing mdp3 version.

In original design, cmdq_pkt_jump() call cmdq_get_shift_pa() every

and pass shift_pa to cmdq_pkt_jump() to prevent frequent function

For cmdq jump command, offset 0 means relative jump and offset 1
