KVM: arm64: vgic: Don't acquire the lpi_list_lock in vgic_put_irq()
The LPI xarray's xa_lock is sufficient for synchronizing writers when
freeing a given LPI. Furthermore, readers can only take a new reference
on an IRQ if it was already nonzero.
Stop taking the lpi_list_lock unnecessarily and get rid of
__vgic_put_lpi_locked().
