Fix truncf for sNaN input
Make line 47 in sf_trunc.c reachable. While converting the double precision function trunc to the single precision version truncf an error was introduced into the special case. This special case is meant to catch both NaNs and infinities, however qNaNs and infinities work just fine with the simple return of x (line 51). The only error occurs for sNaNs where the same sNaN is returned and no invalid exception is raised.
