[PATCH] i915: Remove silly test

[Alan Cox]

From: Alan Cox <alan at linux.intel.com>

drv_priv->gmbus is an array. Comparing it with NULL is somewhat less useful
than a chocolate teapot.

Possibly we should be testing bus != NULL each iteration of the loop
instead ?

gcc could help by warning too!
