[igt-dev] [PATCH i-g-t 3/7] kms_flip: Fix warning related to i915 gem dependence

[Rodrigo Siqueira]

In the kms_flip tests has an igt_fixture that allocates memory for i915
driver with “drm_intel_bufmgr_gem_init()”, which produces the following
warning:

 IGT-Version: 1.23-g8d81c2c2 (x86_64) (Linux: 5.0.0-rc7-VKMS-RULES+ x86_64)
 Using monotonic timestamps
 DRM_IOCTL_I915_GEM_APERTURE failed: Invalid argument
 Assuming 131072kB available aperture size.
 May lead to reduced performance or incorrect rendering.
 get chip id failed: -1 [22]

This commit handles this specific dependence with the i915 driver which
make the kms_flip logs better.
