Subject: [PATCH v2 01/12] soc: mediatek: cmdq: Fix typo of CMDQ_JUMP_RELATIVE

For cmdq jump command, offset 0 means relative jump and offset 1
means absolute jump. cmdq_pkt_jump() is absolute jump, so fix the
typo of CMDQ_JUMP_RELATIVE in cmdq_pkt_jump().

Fixes: 946f1792d3d7 ("soc: mediatek: cmdq: add jump function")
