[PATCH 8/9] drm/radeon: drop RADEON_FENCE_SIGNALED_SEQ v2

["Christian König" <deathsimple@vodafone.de>]

From: Christian König <christian.koenig@amd.com>

It's causing issues with VMID handling and comparing the
fence value two times actually doesn't make handling faster.

v2: rebased on reset changes

Signed-off-by: Christian König <christian.koenig@amd.com>
