[Sound-open-firmware] [PATCH 02/25] dai: reset dai_pos at MMAP_PPOS command

[Keyon Jie]

It reset dai_pos at prepare stage before, which will
make it wrong when the prepare is called more than
one time.

Here move the reset to MMAP_POS command handling,
which should happen at stream allocating stage only.
