SUNRPC: Shrink size of struct rpc_task
Move the field 'tk_rpc_status' so that we eliminate a 4 byte hole in the
structure.
For x86_64, this shrinks the size of the struct by 8 bytes.
'pahole' output before the change:
/* size: 232, cachelines: 4, members: 27 */
/* sum members: 222, holes: 1, sum holes: 4 */
/* sum bitfield members: 8 bits (1 bytes) */
/* padding: 5 */
/* last cacheline: 40 bytes */
'pahole' output after the change:
/* size: 224, cachelines: 4, members: 27 */
/* padding: 1 */
/* last cacheline: 32 bytes */
