The fix is to allocate memory for the QEMUIOVector and struct iovec as part of
the request struct which the IO buffer is part of. The memory for this struct is
guaranteed to be valid till the AIO is completed.

take a void pointer instead of QEMUIOVector* and use a union to hold the
buffer in BlkRwCo.

The fix is to change blk_aio_prwv() to accept a void pointer for the IO buffer
rather than a QEMUIOVector. blk_aio_prwv() passes this through in BlkRwCo and
the
coroutine function casts it to QEMUIOVector or uses the void pointer directly.

keep it consistent with the AIO path.
