myodbc_end is really only usable during Windows DLL unload, since it's not
connection-specific and not thread-safe either.  This bit of brain fade
accounts for our bug #185343 and several bugs filed at mysql.com.

Furthermore, my_end() isn't exported from libmysqlclient anymore.
Hence, best fix is to turn the function into a no-op.
