l2tp: l2tp_debugfs: fix Clang -Wformat warnings
When building with Clang we encounter the following warnings: | net/l2tp/l2tp_debugfs.c:187:40: error: format specifies type 'unsigned | short' but the argument has type 'u32' (aka 'unsigned int') | [-Werror,-Wformat] seq_printf(m, " nr %hu, ns %hu\n", session->nr, | session->ns); - | net/l2tp/l2tp_debugfs.c:196:32: error: format specifies type 'unsigned | short' but the argument has type 'int' [-Werror,-Wformat] | session->l2specific_type, l2tp_get_l2specific_len(session)); - | net/l2tp/l2tp_debugfs.c:219:6: error: format specifies type 'unsigned | short' but the argument has type 'u32' (aka 'unsigned int') | [-Werror,-Wformat] session->nr, session->ns, Both session->nr and ->nc are of type `u32`. The currently used format specifier is `%hu` which describes a `u16`. My proposed fix is to listen to Clang and use the correct format specifier `%u`. For the warning at line 196, l2tp_get_l2specific_len() returns an int and should therefore be using the `%d` format specifier.
