xen-netback: fix refcnt unbalance for 3.10
With the introduction of "xen-netback: Don't destroy the netdev until the vif is shut down" (upstream commit id 279f438e36), vif disconnect and free are separated. However in the backported version reference counting code was not correctly modified, and the reset of vif->irq was lost. If frontend goes through vif life cycle more than once the reference counting is skewed. This patch adds back the missing vif->irq reset line. It also moves several lines of the reference counting code to vif_free, so the moved code corresponds to the counterpart in vif_alloc, thus the reference counting is balanced.
