[Intel-gfx] [PATCH i-g-t] tests/drv_hangman: remove check for other drm clients

[tim.gore at intel.com]

From: Tim Gore <tim.gore at intel.com>

This test will not run on Android as the coreu service
remains running even after the android system is stopped.
Coreu is a client of drm and when the test finds this it
fails an assert.
Coreu is started by the init process and there is no
tidy, non invasive way to stop it (init just restarts it).
Coreu isn't doing anything and would not be expected to
interfere with this test. In addition, all the other
igt tests just rely on the user/test script to ensure
that there are no other drm clients, so this test can
do the same. On Android we must rely on coreu being
dormant when this test runs.
