drm/msm: remove checks for return value of drm_debugfs_create_files()
Since commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_files never
fails and only returns 0. Therefore, the unnecessary checks for its
return value and error handling in various debugfs_init() functions in
drm/msm and have the functions return 0 directly.
v2: have debug functions return 0 instead of void to avoid build
breakage and ensure standalone compilation.
