Calling gbm_bo_create() with format == GBM_BO_FORMAT_ARGB8888 completes
successfully. However reading back the format via gbm_bo_get_format()
returns GBM_BO_FORMAT_XRGB8888.

The problem seems to be that the bo internal structure is initialized to
zero by calloc, but the format field is never set by gbm_dri_bo_create,
so it stays zero (GBM_BO_FORMAT_XRGB8888) even when the real image
format is something different.

Should be a simple fix in gbm_dri_bo_create(). Just add:
  bo->base.base.format = gbm_dri_to_gbm_format(dri_format);
