KVM: arm64: vgic-its: Generalize use of vgic_get_irq_kref
Instead of sprinkling raw kref_get() calls everytime we cannot
do a normal vgic_get_irq(), use the existing vgic_get_irq_kref(),
which does the same thing and is paired with a vgic_put_irq().
vgic_get_irq_kref is moved to vgic.h in order to be easily shared.
