Bo Chen 0686045290 vmm: interrupt: Allocate GSIs for MSI/MSI-X interrupt vectors lazily ...

Previously, GSIs were eagerly allocated for all MSI-X vectors a device
advertises (i.e. the maximum the device can support). This can easily
exhaust KVM_MAX_IRQ_ROUTES (4096) with modern NVMe devices that support
up to 2048 MSI-X vectors.

Defer GSI allocation to the first time an interrupt vector is
unmasked. The EventFd is still created eagerly since external
components (e.g. VFIO) need it at device init time.
