ixgbe: Remove tail write abstraction and add missing barrier
This change cleans up the tail writes for the ixgbe descriptor queues. The
current implementation had me confused as I wasn't sure if it was still
making use of the surprise remove logic or not.
It also adds the mmiowb which is needed on ia64, mips, and a couple other
architectures in order to synchronize the MMIO writes with the Tx queue
_xmit_lock spinlock.
