[PATCH] Fix compilation warning of clone-multi-ptrace.c

[Wenji Huang]

Hi,

There is warning: control reaches end of non-void function in compiling 
clone-multi-ptrace.c (utrace test case).  The warning is treated as 
error so as to failed making. A return valued is needed in function 
grandchild_func.

Regards,
Wenji
