Always check CFX_RenderDevice::CreateCompatibleBitmap() return value

By checking the return value from CreateCompatibleBitmap(), there is no
need to do a separate GetBuffer() check in
CPDF_RenderStatus::GetBackdrop(). Fix some nits there as well.

In CPDF_DeviceBuffer::OutputToDevice(), prevent a potential crash in
case CreateCompatibleBitmap() fails.
