drm: msm: adreno: use DEFINE_DEBUGFS_ATTRIBUTE with debugfs_create_file_unsafe()
Using DEFINE_DEBUGFS_ATTRIBUTE macro with debugfs_create_file_unsafe()
function in place of the debugfs_create_file() function will make the
file operation struct "reset" aware of the file's lifetime. Additional
details here: https://lists.archive.carbon60.com/linux/kernel/2369498
