block: cfq_cpd_alloc() should use @gfp

Browse Source 
commit ebc4ff661fbe76781c6b16dfb7b754a5d5073f8e upstream.

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.
