i2c: core: Use generic_handle_irq_safe() in i2c_handle_smbus_host_notify().
The i2c-i801 driver invokes i2c_handle_smbus_host_notify() from his
interrupt service routine. On PREEMPT_RT i2c-i801's handler is forced
threaded with enabled interrupts which leads to a warning by
handle_irq_event_percpu() assuming that irq_default_primary_handler()
enabled interrupts.
i2c-i801's interrupt handler can't be made non-threaded because the
interrupt line is shared with other devices.
Use generic_handle_irq_safe() which can invoked with disabled and enabled
interrupts.
