dlls/msi/streams.c -- simplify and constify

[Gerald Pfeifer]

While removing the dead code I noticed that we can actually also
strengthen the const-ness of this function.

Gerald

ChangeLog:
Remove a check which never could trigger (due to the domain of the
variable in question) and increase const-ness of STREAMS_CreateView().
