[SCSI] zfcp: Introduce new kmem_cache for FC request and response data

A data buffer that is passed to the hardware must not cross a page
boundary. zfcp uses a series of kmem_caches to align the data to not
cross a page boundary. Introduce a new kmem_cache for the FC requests
sent from the zfcp driver and use it for the ELS ADISC data.  The goal
is to migrate to the FC kmem_cache in later patches and remove the
request specific kmem_caches.
