drm/radeon: Prevent multiple debug error lines on suspend
Fix to avoid multiple debug error lines printed on every suspend by Radeon driver's debugfs.
radeon_debugfs_init() calls debugfs_create_file() for every ring.
This results in printing multiple error lines to the screen and dmesg similar to this:
[ 92.378726] debugfs: File 'radeon_ring_gfx' in directory '0000:00:01.0' already present!
[ 92.378732] debugfs: File 'radeon_ring_cp1' in directory '0000:00:01.0' already present!
[ 92.378734] debugfs: File 'radeon_ring_cp2' in directory '0000:00:01.0' already present!
[ 92.378737] debugfs: File 'radeon_ring_dma1' in directory '0000:00:01.0' already present!
[ 92.378739] debugfs: File 'radeon_ring_dma2' in directory '0000:00:01.0' already present!
[ 92.380775] debugfs: File 'radeon_ring_uvd' in directory '0000:00:01.0' already present!
[ 92.406620] debugfs: File 'radeon_ring_vce1' in directory '0000:00:01.0' already present!
[ 92.406624] debugfs: File 'radeon_ring_vce2' in directory '0000:00:01.0' already present!
Patch v1: The fix was to run lookup() for the file before trying to (re)create that debug file.
Patch v2: Call the radeon_debugfs_init() only once when radeon ring is initialized (as suggested
