[PATCH 4/6] winex11.drv: Reject changing non-primary adapter settings.

[Zhiyi Zhang]

Changing non-primary adapter settings is currently unsupported.
Reject non-primary adapter settings changes so that when users
want to change the settings of non-primary adapters, the primary
adapter settings don't get changed unintentionally.
