accel/habanalabs/gaudi2: fix spmu mask creation
event_types_num received from the user can be 0. In that case, the
event_mask should be 0.
In addition, to create a correct mask we need to match the number
of event types to the bit location such that bit 0 represents a single
event type, bit 1 represents 2 types and so on.
