[Mesa-dev] [PATCH] i965: Don't call abort() on an unknown device.

[Kenneth Graunke]

If we don't recognize the PCI ID, we can't reasonably load the driver.
However, calling abort() is quite rude - it means the application that
tried to initialize us (possibly the X server) can't continue via
fallback paths.  We already have a more polite mechanism - failing to
create the context.  So, just use that.

While we're at it, improve the error message.
