[PATCH 14/24] drm/radeon: rework recursive gpu reset handling

From: Christian K?nig Instead of all this humpy pumpy with recursive mutex (which also fixes only halve of the problem) move the actual gpu reset out of the fence code, return -EDEADLK and then reset the gpu in the calling ioctl function. v2: Split removal of radeon_mutex into separate patch.
