qe missing config reference to if_uba

[Josh Moyer <JMoyer%nodomain.net@localhost>]

Hello port-vax!
I was trying to compile a custom kernel on my VAXserver 3x00/KA655 and found that the linking was failing due to an unavailable reference.  I propose the following patch to resolve the issue:

diff --git a/sys/dev/qbus/files.uba b/sys/dev/qbus/files.uba
index 20c6e0c..2503b77 100644
