David Vrabel c8a4d29988 xen-netback: notify immediately after pushing Tx response.
This fixes a performance regression introduced by
7fbb9d8415 (xen-netback: release pending
index before pushing Tx responses)

Moving the notify outside of the spin locks means it can be delayed a
long time (if the dealloc thread is descheduled or there is an
interrupt or softirq).
