i915: Fall back to GEM_MMAP_GTT if GEM_MMAP fails DRM_IOCTL_I915_GEM_MMAP mmaps the underlying shm file and returns a user space address directly, ie, doesn't go through mmap. If we try that on a dma-buf that doesn't have a shm file, i915.ko returns ENXIO. Fall through to DRM_IOCTL_I915_GEM_MMAP_GTT in that case, which will mmap on the drm fd instead. BUG=b:167236452 TEST=dmabuf_test from drm-tests passes Change-Id: I41cd0b0150d2d489bd055e23f4495cd13624b831 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/minigbm/+/2561378 Tested-by: Kristian H.
