drm/i915/bdw: Return -ENONENT on default ctx destroy

This was an accidental "ABI" change introduced during PPGTT:

commit 0eea67eb26000657079b7fc41079097942339452
Author: Ben Widawsky <ben@bwidawsk.net>

    drm/i915: Create a per file_priv default context

The failure test application actually tests the return type. The other
option is to simply change the test.
