open_istream: remove unneeded check for null pointer
'st' is allocated via xmalloc a few lines before and passed to the stream opening functions. The xmalloc function is written in a way that either 'st' is allocated valid memory or xmalloc already dies. The function calls to open_istream_* do not change 'st', as the pointer is passed by reference and not a pointer of a pointer. Hence 'st' cannot be null at that part of the code.
