    Fix usage of inferior_ptid in two thread_alive implementations
    
    While inspecting some target code, I noticed that in these two
    implementations of thread_alive, inferior_ptid is referenced directly
    instead of using the ptid passed as parameters.  I guess that it is
    wrong, although I can't really test it in both cases.
    
    gdb/ChangeLog:
    
    	* bsd-uthread.c (bsd_uthread_thread_alive): Use ptid instead of
    	inferior_ptid.
    	* go32-nat.c (go32_thread_alive): Likewise.
