[PATCH] drm/i915: Remove BUG_ON from i915_gem_evict_something

[Seth Forshee]

BugLink: https://bugs.launcpad.net/bugs/828550

According to Chris Wilson this BUG_ON was just paranoia and never
something the kernel should explode on. He later removed it in
upstream commit e39a01501b228e1be2037d5bddccae2a820af902. So let's
just remove it.
