habanalabs/gaudi: fix incorrect MME offset calculation

Once FW raised an event following a MME2 QMAN error, the driver should
have gone to the corresponding status registers, trying to gather more
info on the error, yet it was accidentally accessing MME1 QMAN address
space.

Generally, we have x4 MMEs, while 0 & 2 are marked MASTER, and
1 & 3 are marked SLAVE. The former can be addressed, yet addressing
the latter is considered an access violation, and will result in a
hung system, which is what unintentionally happened above.
Note that this cannot happen in a secured system, since these registers
are protected with range registers.
