    Remove unused code block in inf_ptrace_target::wait
    
    Remove unused PT_GET_PROCESS_STATE block. It used to be used
    by OpenBSD, but it is now reimplemented independently in
    obsd-nat.c.
    
    gdb/ChangeLog:
    
           * inf-ptrace.c (inf_ptrace_target::wait): Remove
           `PT_GET_PROCESS_STATE' block.
