Kernel: Set IRQHandler m_shared_with_others when the irq is shared

Browse source 
If IRQHandler's IRQ is shared, then disable_irq() should not call the
controller to disable that IRQ as some other device might be using it.
IRQHandler had a private variable to indicate if it is being shared:
m_shared_with_others but it was never modified even if the IRQ was
shared.

Add a new member function set_shared_with_others() to enable/disable
m_shared_with_others member of IRQHandler class. This function is
called when an IRQHandler is being added/removed as a part of
SharedIRQHandler.
