ext4: avoid -Wformat-security warning

check_igot_inode() prints a variable string, which causes a harmless
warning with 'make W=1':

fs/ext4/inode.c:4763:45: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
 4763 |         ext4_error_inode(inode, function, line, 0, err_str);

Use a trivial "%s" format string instead.
