MFC r261535:
Add support for MegaRAID Fury cards. The main change needed to boot from a
9341-4i controller was to ensure that scatter/gather lists are ended with
an end-of-list marker. Both the mrsas and Linux megaraid_sas drivers use
this marker with Invader cards as well, so we do the same thing, though
it is apparently not strictly necessary.
