[SCSI] ibmvfc: Improve ibmvfc_async_desc memory layout
By changing field ordering we can avoid a couple of memory holes in the tables that use the ibmvfc_async_desc structure. Signed-off-by: Robert Jennings <rcj@linux.vnet.ibm.com> Acked-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
