host_command: Change host command return value to enum ec_status
If the host command handler callback function returns an int, it's easy
to accidentally mix up the enum ec_error_list and enum ec_status types.
The host commands always expect an enum ec_status type, so we change the
return value to be of that explicit type. Compilation will then fail if
you accidentally try to return an enum ec_error_list value.
Ran the following commands and then manually fixed up a few remaining
instances that were not caught:
git grep --name-only 'static int .*(struct host_cmd_handler_args \*args)' |\
xargs sed -i 's#static int \(.*\)(struct host_cmd_handler_args \*args)#\
static enum ec_status \1(struct host_cmd_handler_args \*args)##'
git grep --name-only 'int .*(struct host_cmd_handler_args \*args)' |\
xargs sed -i 's#int \(.*\)(struct host_cmd_handler_args \*args)#\
enum ec_status \1(struct host_cmd_handler_args \*args)##'
