Fix dlfcn/failtestmod.c warning.

Browse Source 
This patch fixes a "set but not used" warning from
dlfcn/failtestmod.c.  A variable is used only to store the return
value from dlsym.  As I understand this test, the point is simply to
do a sequence of load / unload operations in a loop, and all that
matters here is that dlsym gets called and returns without crashing,
not what its return value is.  So this patch removes the assignment to
a variable.

Tested for x86_64.

	* dlfcn/failtestmod.c (constr): Do not store result of dlsym in a
	variable.
