perf debug: Avoid stack overflow in recursive error message
[ Upstream commit bda840191d2aae3b7cadc3ac21835dcf29487191 ]
In debug_file, pr_warning_once is called on error. As that function
calls debug_file the function will yield a stack overflow. Switch the
location of the call so the recursion is avoided.
