The idea is that the first time you call our stub function, it does
call LoadProcAddress.  Then it rewrites the stub to simply jump to the
new address, and jumps back to the stub!  The second time the stub is
called, it has nothing but the jump in it.

You can't just call the function, because you don't know what the
parameters look like (well, we do, but it's not automatic like the jmp
is, and jmp is faster).
