…large error values. Balance the call to allocateBufferIn with a call to deallocateBufferIn. When an error value is small, the missing deallocateBufferIn doesn't do anything. But when the error value is a larger struct that doesn't fit inline, we need deallocateBufferIn to avoid leaking the allocation. rdar://109933822
