isci: Save the suspension hint for upcoming suspensions.
In the case of a suspend call while in SCI_RNC_POSTING or INVALIDATING states, the LLHANG detect needed to be saved so the upcoming suspension would enable it correctly. The unused suspend callback parameters were removed. Signed-off-by: Jeff Skirvin <jeffrey.d.skirvin@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
