[PATCH] uml: mostly const a structure
The chan_opts structure is mostly const, and needs no locking. Comment the
lack of locking on the one field that can change.
Make all the other fields const. It turned out that console_open_chan didn't
use its chan_opts argument, so that is deleted from the function and its
callers.
