venus: fix misaligned bo_flags between import and query

venus: fix misaligned bo_flags between import and query

For importing an dma_buf fd, export info is not required. Leaving the
bo_flags missing VIRTGPU_BLOB_FLAG_USE_SHAREABLE bit as well as the
VIRTGPU_BLOB_FLAG_USE_CROSS_DEVICE bit. Upon querying fd properties,
DMA_BUF handle type will be specified which generates a new bo_flags
not matching the prior one.

This patch aligns the above 2 bits for the dma_buf import path.

Test: vkGetAndroidHardwareBufferPropertiesANDROID should succeed with
      a valid AHB with AHARDWAREBUFFER_FORMAT_BLOB format.
