Subject: [PATCH 08/21] drm/etnaviv: remove check for return value of drm_debugfs function

Since commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_file only
returns 0, and there is no need to check the return value.
This change therefore removes the check and error handling in
etnaviv_debugfs_init() and also makes the function return void.
