[SCSI] mpt fusion: removing references to hd->ioc
Cleaning up code by accesing the ioc pointer directly instead of via hd->ioc. In the future, most data members of struct MPT_SCSI_HOST will be either deleted or moved to struct MPT_ADAPTER. Signed-off-by: Eric Moore <Eric.Moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
