bug#46111: Reverting fns.c hash function due to OpenBSD/SPARC64 compile breaking

[Ahmed Khanzada]

I'm not an expert on C, OpenBSD, or SPARC64, but I did notice
emacs-current was not compiling.

During a gmake, bootstrap-emacs would get a SIGBUS and fail. Running
gdb led me to the hash_string function where it seemed to be failing.

Reverting the hash_string function to a previous version seems to have
fixed the issue.

If I had to guess, it may have something to do with SPARC64 alignment.

I don't have an updated AMD64 OpenBSD box running at the moment, but if you
would like me to test there, I could find a way.

I understand that reverting this function might not be the best way
forward, but wrote a patch just in case that reverts hash_string to an
earlier version that compiles on OpenBSD/SPARC64.

I am already signed all my GNU contributor docs.
