ixgbe: residual fix about resetting big Tx queues

Browse Source 
Index overflow when resetting big queues was partially fixed in
bcf457f8c0 (ixgbe: fix index overflow when resetting big Tx queues)
and better fixed in
e8ae856140 (igb/ixgbe: fix index overflow when resetting big queues)

But this version (1.5.2r0) has residues of the initial fix from 1.5.1r0.
