Roman Stratiienko 4f7758ffa1 minigbm: Use dmabuf inode as unique buffer id instead of handle 
Handle has some limits and can't be used as unique buffer ID on systems
where display controller can scanout from CMA but GPU can work with both
CMA and VRAM.

Such systems have DRM/KMS and DRM/GPU drivers separated.
GBM frontend is always expecting handle for DRM/KMS driver.
In such system any attempt of importing the buffer with more
than 1 contiguous chunk into DRM/KMS driver will fail.

Using dma-buf inode as unique buffer ID is a common practice for
a last several years starting from [this kernel patch][1].
