PCI: modify SB700 SATA MSI quirk 



SB700 SATA MSI bug will be fixed in SB700 revision A21 at hardware
level, but the SB700 revision older than A21 will also be found in the
market.  This patch modify the original quirk commit
bc38b411 instead of withdrawing it.
The patch also removes quirk to 0x4395 because 0x4395 is SB800 device
ID.
