Be more conservative in using READ CAPACITY(16) command. Previous code
checked PROTECT bit in INQUIRY data for all SPC devices, while it is defined
only since SPC-3. But there are some SPC-2 USB devices were reported, that
have PROTECT bit set, return no error for READ CAPACITY(16) command, but
return wrong sector count value in response.
