block: cfq_cpd_alloc() should use @gfp

cfq_cpd_alloc() which is the cpd_alloc_fn implementation for cfq was
incorrectly hard coding GFP_KERNEL instead of using the mask specified
through the @gfp parameter. This currently doesn't cause any actual
issues because all current callers specify GFP_KERNEL. Fix it.
