[igt-dev] [PATCH i-g-t v4 06/14] i915/gem_unfence_active_buffers.c: Remove librdm dependency

[Dominik Grzegorzek]

Use intel_bb / intel_buf to remove libdrm dependency.
The difference between offsets proposed from kernel using intel_bb
instead of libdrm is caused by EXEC_OBJECT_SUPPORTS_48B_ADDRESS set on
every object.
