NFSv4.1 Fix gdia_maxcount calculation to fit in ca_maxresponsesize
The GETDEVICEINFO gdia_maxcount represents all of the data being returned within the GETDEVICEINFO4resok structure and includes the XDR overhead. The CREATE_SESSION ca_maxresponsesize is the maximum reply and includes the RPC headers (including security flavor credentials and verifiers). Split out the struct pnfs_device field maxcount which is the gdia_maxcount from the pglen field which is the reply (the total) buffer length.
