Fixed changing login server for newer client versions

Client no longer uses login.cfg and the addresses are hardcoded, theres
a piece of code that malloc()'s some new space and writes the hardcoded
value (x2, main and backup), and pointers to point to the new mallocd
memory (x2, main and backup),.

So...

Read the ptr address;
NOP just the part that copies the malloc'd memory to the pointer
alloc memory space for own login server
set pointer main+backup to our alloc
