The reserved space code was not cleaning up properly in the case where
the intel_ring_begin() call failed. This led to WARN_ONs firing about
a double reserve call when running the gem_reset_stats IGT test.
*reserve_space() failure leads to a i915_gem_request_cancel() which
calls intel_ring_reserved_space_cancel().
