wmix: do not risk a crash (null-pointer-dereference) if $DISPLAY is not set
The original code merely assumed that an XOpenDisplay failure was caused
only by incapacity to connect to the X server, but if $DISPLAY was not set
then the fprintf would be given a NULL pointer which it may not appreciate
(depending on the libc in use).
Let's avoid that case and try to provide more info to help the user.
