ixgbe: Fix return of invalid txq
commit fdd3d631cddad20ad9d3e1eb7dbf26825a8a121f upstream.
a developer had complained of getting lots of warnings:
"eth16 selects TX queue 98, but real number of TX queues is 64"
http://www.mail-archive.com/e1000-devel@lists.sourceforge.net/msg02200.html
As there was no follow up on that bug, I am submitting this
patch assuming that the other return points will not return
invalid txq's, and also that this fixes the bug (not tested).
