isci: fix fragile/conditional isci_host lookups
A domain_device can always reference back to ->lldd_ha unlike local lldd
structures. Fix up cases where the driver uses local objects to look up the
isci_host. This also changes the calling conventions of some routines to
expect a valid isci_host parameter rather than re-lookup the pointer on entry.
Incidentally cleans up some macros that are longer to type than the open-coded
equivalent:
isci_host_from_sas_ha
isci_dev_from_domain_dev
