Andrew Gallatin 6d914a32ff Much to my surprise, IFQ_DRV_DEQUEUE() can return a null mbuf even if 
!IFQ_DRV_IS_EMPTY().  Taking this into account,  I re-structured the
transmit routine so as to avoid adding another if/then in the
critical path.

Thanks to brueffer for showing my how to test with altq/pf.
