[PATCH 1/1] oleauto: dereference VT_RECORD|VT_BYREF in place

[Kevin Puetz]

From: Kevin Puetz

VariantCopyInd allows pvargDest == pvargSrc in order to dereference in place
To avoid confusing the source values and a partially-written destination,
wine's implementation makes a shallow copy and uses that as pSrc.

However, the call to VARIANT_CopyIRecordInfo did not use this,
leading to it copying from the zeroed-out memory it just allocated.
