habanalabs/gaudi2: mark PCIE access error as fatal
F/W events are enabled in a late phase of the device init, so an event
for a PCIE access error during the init, can be received after the init
is already done and considered as successful.
A resulting device reset, which does the same H/W init, can end
similarly with this event right after the reset is done and considered
as successful, and a loop of this sequence can continue.
To avoid it mark the PCIE access error as a fatal event, so after 2
consecutive events no more resets will be done.
