Fix race condition in red_get_data_chunks_ptr

Do not read multiple times data from guest as this can be changed by
other guest vcpus. This causes races and security problems if these
data are used for buffer allocation or checks.

Actually, the 'data' member can't change during read as it is just a
pointer to a fixed array contained in qxl. However, this change will
make it clear that there can be no race condition.
