[PATCH 19/27] drm/i915: Fix bug in user proto-context creation that leaked contexts

[Matthew Brost]

Set number of engines before attempting to create contexts so the
function free_engines can clean up properly.

Fixes: d4433c7600f7 ("drm/i915/gem: Use the proto-context to handle create 
parameters (v5)")
