Maxime Henrion c7d24cc1a2 Fix a race condition that was introduced since pccbb interrupts are ...

flag'ed INTR_MPSAFE.  In ep_if_start(), use the IF_DEQUEUE macro to
grab the next mbuf to send, and use IF_PREPEND if the card is busy
and we actually can't handle it right now.

The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either.  It was later assuming that IF_DEQUEUE would
give him this same mbuf.
