cpu: fixed unused variable on fast binary

Browse Source 
When gem5.fast is compiled, an error on a variable
used only for debug purposes is raised:

build/X86/cpu/o3/mem_dep_unit_impl.hh:262:19: error: unused variable 'producing_store' [-Werror=unused-variable]
         for (auto producing_store : producing_stores)

This patch remove the variable when *.fast is used.
