vmdk: Fix zero cluster allocation
m_data must contain valid data even for zero clusters when no cluster
was allocated in the image file. Without this, zero writes segfault with
images that have zeroed_grain=on.
For zero writes, we don't want to allocate a cluster in the image file
even in compressed files.
