kmsallocator: Update GstVideoInfo.size when extrapolating

When we guess the strides, we need to also update the GstVideoInfo.size
otherwise the memory size will be set to something smaller then needed.
This was causing crash with the DMABuf exportation, since we would not
mmap() a large enough buffer.
