drm/i915: fix modeset devname allocation + agp init return check.
devname needs to be allocated before the irq is installed, so the irq routines get the correct name in /proc. Also check the return value from the AGP init function, and fixup the exit points. Signed-off-by: Dave Airlie <airlied@redhat.com>
