From: Priyanka Dandamudi <priyanka.dandamudi at intel.com>

Test is trying to hit a race condition by submitting same buffer object
between two contexts on different rings.Similar scenario can be found in
gem_ctx_param and gem_exec_ctx.This test doesn't add anything to other
tests.So,removing the test.
