vmdk: fix metadata write regression
Commit "cdeaf1f vmdk: add bdrv_co_write_zeroes" causes a regression on writes. It writes metadata after every write instead of doing it only once for each cluster. vmdk_pwritev() writes metadata whenever m_data is set as valid so this patch sets m_data as valid only when we have a new cluster which hasn't been allocated before or a zero grain.
