raw_co_zone_append() sets "s->offset" where "BDRVRawState *s". This pointer is used later at raw_co_prw() to save the block address where the data is written.When multiple IOs are on-going at the same time, a later IO's raw_co_zone_append() call over-writes a former IO's offset address before raw_co_prw() completes. As a result, the former zone append IO returns the initial value (= the start address of the writing zone), instead of the proper address. Fix the issue by passing the offset pointer to raw_co_prw() instead of passing it through s->offset. Also, remove "offset" from BDRVRawState as there is no usage anymore.

This smells like a -stable material. Please let me know if it is not. Thanks, /mjt
