Quick fix for profiling after I broke it in rev. 1.68.

The profiling system needs some initialisation after module
registration (hs_add_root()).  Since module registration now happens
later, the profiling system was getting initialised too early before
any cost centers had been registered.  This is a quick fix; we still
can't handle multiple hs_add_root()s with profiling.
