have to adjust for whether he have a "small" or "large" mode sense response.
sd_scsibus_getcache(), sd_scsibus_setache(): Set SMS_DBD so that we don't
have to deal with block descriptors here.
sd_scsibus_mode_sense(): Add a new parameter, "int *big", which tells the
caller whether it's a small or large header.
sd_scsibus_get_parms(), sd_scsibus_getcache(), sd_scsibus_setcache(): Use
the "big" value to find the data following the mode sense header correctly.
sd_scsibus_mode_sense(): Disable PQUIRK_NOBIGMODESENSE for now, as the
reasons for it were dubious and most likely fixed now.
sd_scsibus_get_parms(): Now that we're actually locating the right data,
check the returned page code to see if it's correct before using the mode
page info.
sd_scsibus_get_parms(): Get the rotational rate from the flex geometry page
too, if present.
XXX sd_scsibus_get_{opt,simplifiedparms}() need some work.
