media/gpu/v4l2IP: Set output queue's storage type to the storage type…

… of output VideoFrame

This fixes a bug of V4L2ImageProcessor on output queue's storage
type. The output queue's storage type is V4L2_MEMORY_DMABUF if
import mode. But it should follow the configured storage type of
output VideoFrame in import mode.

Bug: None
Test: ip_test --gtest_filter=NV12* on kukui
