accel/habanalabs/gaudi2: read preboot status after recovering from dirty state

Browse source

[ Upstream commit a0d866bab1 ]

Dirty state can occur when the host VM undergoes a reset while the
device does not. In such a case, the driver must reset the device before
it can be used again. As part of this reset, the device capabilities
are zeroed. Therefore, the driver must read the Preboot status again to
learn the Preboot state, capabilities, and security configuration.
