[PATCH v2 1/5] lib/igt_gt: Fix forcewake open

[Lucas De Marchi <lucas.demarchi@intel.com>]

File from the kernel side is read-only and should be open as such:

	debugfs_create_file("i915_forcewake_user", S_IRUSR, minor->debugfs_root,
			    to_i915(minor->dev), &i915_forcewake_fops);

Apparently it doesn't matter for just opening it:

	openat(AT_FDCWD, "/sys/kernel/debug/dri/0", O_RDONLY) = 5
	openat(5, "i915_forcewake_user", O_WRONLY) = 6

But RDONLY is sufficient. Let's stick to the file permission.
