isci: unify request data structures
Make scic_sds_request a proper member of isci_request. Also let's us
get rid of the dma pool object size tracking since we now know that all
requests are sizeof(isci_request). While cleaning up the construct
routine incidentally replaced SCI_FIELD_OFFSET with offsetof.
