Subject: drm/i915: Clear the in-use marker on execbuf failure
From: Chris Wilson <chris@chris-wilson.co.uk>
commit e659d14ed48096f87a678e7ebbdf286a817b4d0e upstream.
If we fail to unbind the vma (due to a signal on an active buffer that
needs to be moved for the next execbuf), then we need to clear the
persistent tracking state we setup for this execbuf.
Fixes: c7c6e46f913b ("drm/i915: Convert execbuf to use struct-of-array packing for critical fields")
Testcase: igt/gem_fenced_exec_thrash/no-spare-fences-busy*
