From SBC-4: BYTCHK = 0 means that the Data-Out buffer contents
must not be used. BYTCHK = 1 means that the Data-Out buffer must
be compared against the data on the storage medium. Hence set
BYTCHK to 1 if EDTL != 0.

Avoid that the DPO / DPOFUA tests triggers a NULL pointer dereference
if the MODE SENSE command in these tests fails.

Remove the flags tests for READ* and replace them with a test for the DPO
and FUA bits.
IF the device claims DPOFUA support in modesense then the READ* CDBs
MUST allow these two flags. IF the device does NOT claim DPOFUA then any
READ* CDB with these flags must fail with invalod field in cdb.
