Following patch fixes improper RX ring management E1000 code
Changes from version 2:
Commit message beautification
Changes from version 1:
1st patch changed so it drops check_rxov field because it is redundant and
leads to race conditions
See commit description for details
2nd patch (live migration) dropped because corresponding field got deleted
Also I've made short experiment with an Intel adapter controlled by e1000e
driver.
Indeed I saw no RX indication attempt when RX ring's RDH and RDT are equal.

e1000: drop check_rxov, always treat RX ring with RDH == RDT as empty
