Markus Armbruster 64af7a8bad qemu-option: Replace opt_set() by cleaner opt_validate()
opt_set() frees its argument @value on failure.  Slightly unclean;
functions ideally do nothing on failure.

To tidy this up, move opt_create() from opt_set() into its callers,
along with the cleanup.  Rename opt_set() to opt_validate(), noting
its similarity to qemu_opts_validate().  Drop redundant parameter
@opts; use opt->opts instead.
