[PATCH 3/3] habanalabs: correctly report inbound pci region cfg error

[Oded Gabbay]

From: Ofir Bitton <obitton@xxxxxxxxx>

During inbound iATU configuration we can get errors while
configuring PCI registers, there is a certain scenario in which these
errors are not reflected and driver is loaded with wrong configuration.
