Before next packet exist, the previous packet has no information of where to jump to, so append nop command first. When next packet exist, change nop command to jump command. For mediatek drm driver, it never has next packet, so appending nop command is redundant. Because cmdq_pkt_finalize() would append nop command, so change calling cmdq_pkt_finalize() to cmdq_pkt_eoc() to prevent append redundant nop command.
