msm: camera: isp: Get packet opcode from hw manager

While processing the user space submitted isp packet,
isp context need to know the packet opcode.
Get the opcode from the hw manager than the direct accessing the
opcode from packet.
Ife umd sends different opcodes then tfe umd. Both ife and tfe kernel
packet opcodes are same. So hw manager can consume this differences.
