MFC 366584: Don't invoke semunload() if seminit() fails during MOD_LOAD.

The module handler code invokes a MOD_UNLOAD event immediately if
MOD_LOAD fails.  The result was that if seminit() failed, semunload()
was invoked twice.  semunload() is not idempotent however and would
try to remove it's process_exit eventhandler twice resulting in a
panic.
