[PATCH 02/14] accel/habanalabs/gaudi2: include block id in ECC error reporting

[Oded Gabbay <ogabbay@xxxxxxxxxx>]

From: Ofir Bitton <obitton@xxxxxxxxx>

During ECC event handling, Memory wrapper id was mistakenly
printed as block id. Fix the print and in addition fetch the actual
block-id from firmware.
