[PATCH] connector: some fixes for ia64 unaligned access errors

On ia64, the various functions that make up cn_proc.c cause kernel
unaligned access errors.

If you are using these, for example, to get notification about all tasks
forking and exiting, you get multiple unaligned access errors per process.

Use put_unaligned() in the appropriate palces to fix this.
