Fix libgfortran/intrinsics/system_clock.c

[Andreas Jaeger <aj at suse dot de>]

Looking at these two warnings:
/cvs/gcc/libgfortran/intrinsics/system_clock.c:70: warning: ‘cnt’ may be used uninitialized in this function
/cvs/gcc/libgfortran/intrinsics/system_clock.c:146: warning: ‘cnt’ may be used uninitialized in this function

I noticed that the warning is correct - we do miss a return statement!

Ok to commit?  Tested on Linux/x86-64,

Andreas

	* intrinsics/system_clock.c (system_clock_4, system_clock_8): Add
	missing returns, reformat a bit.
