Remove the magic mfi_array is 288 bytes and just use the sizeof the array since it is not 288 bytes. Change reporting of a "SYSTEM" disk to "JBOD" to match LSI MegaCli and firmware reporting. This means that fiutil command to "create jbod" is now a little confusing since a RAID per drive is not really what LSI defines JBOD to be. This should be fixed in the future and support added to really create LSI JBOD and enable that feature on cards that support it.
