drm/i915: Restore full symmetry in i915_driver_modeset_probe/remove 

Commit 2d6f6f359f ("drm/i915: add i915_driver_modeset_remove()")
claimed removal of asymmetry in probe() and remove() calls, however, it
didn't take care of calling intel_irq_uninstall() on driver remove.
That doesn't hurt as long as we still call it from
intel_modeset_driver_remove() but in order to have full symmetry we
should call it again from i915_driver_modeset_remove().

Note that it's safe to call intel_irq_uninstall() twice thanks to
commit b318b82455 ("drm/i915: Nuke drm_driver irq vfuncs").  We may
only want to mention the case we are adding in a related FIXME comment
provided by that commit.  While being at it, update the name of
function mentioned as calling it out of sequence as that name has been
changed meanwhile by commit 78dae1ac35 ("drm/i915: Propagate
"_remove" function name suffix down").
