[PATCH 4.4 306/312] bna: add missing per queue ethtool stat

[Greg Kroah-Hartman]

From: Ivan Vecera <ivecera@xxxxxxxxxx>

commit 2835d2d9e366a2985b24051d228333bfba82f3a7 upstream.

Commit ba5ca784 "bna: check for dma mapping errors" added besides other
things a statistic that counts number of DMA buffer mapping failures
per each Rx queue. This counter is not included in ethtool stats output.

Fixes: ba5ca784 "bna: check for dma mapping errors"
