Allow to open device without read check.

Browse Source 
In some specific situation we do not want to read the devices
before initialization.

Here it is integrity checking that will produce warning, because
the device is not yet initialized.

Used only in wipe function (here we must use direct-io anyway)
and expect the device is capable of direct-io.
