[Intel-gfx] [PATCH v2] drm/i915/ctx: Remove bad invariant

[Ben Widawsky]

It's not that the assertion is incorrect, but rather that we can call
do_destroy early in loading, and we will falsely BUG().

Since contexts have been in for a while now, and in the internal APIs
are pretty stable, it should be fairly safe to remove this.

v2: Remove unused dev_priv, and dev
