Subject: [PATCH][next] drm/i915: Fix inconsistent IS_ERR and PTR_ERR

Fix inconsistent IS_ERR and PTR_ERR in i915_gem_object_copy_blt().

The proper pointer to be passed as argument to PTR_ERR() is vma[1].

This bug was detected with the help of Coccinelle.

Fixes: 6b05030496f7 ("drm/i915: Convert i915_gem_object/client_blt.c to use ww locking as well, v2.")
