[PATCH i-g-t] lib/igt_kmod: Stop unloading drm

[Lucas De Marchi]

When testing i915, if there's another driver present, unloading i915 may
cause the other driver to unload and let developers chasing ghosts when
they think it was caused by i915.

Hopefully fix the ATSM testing where AST driver is also bound to a
a device.

After this change, running i915_module_load at reload doesn't cause ast to
be unloaded, but I couldn't check it really fixes the issue since I
couldn't reproduce it.
