i2o: fix notifiers when max_drivers is configured

Browse Source 
Maximum number of I2O drivers which could be registered is configurable by
max_drivers module parameter.

But the module parameter is ignored and default value (I2O_MAX_DRIVERS = 8)
is used in the loops to notify all registered drivers.
