[PATCH v2 0/1] MR8298: ole32: Don't get metafile extent if there is no metafile.

[Yuxuan Shui (＠yshui)]

If entry->stgmedium.hEnhMetaFile is NULL, the data_size we get will be 0, we
then allocate 0 bytes for data, but expect it to contain at least a
METAFILEPICT, resulting in reading out-of-bound.
