Log Message:
Pull up the following revisions(s) (requested by bouyer in ticket #1694):
        sys/dev/pci/if_age.c:   revision 1.40 via patch

- age_init() is called from age_watchdog() which is in interrupt context; we
can't sleep here or we get a DIAGNOSTIC panic when age_watchdog() fires.
- More correct bus_dma(9) usage in age_encap()
- Introduce a age_shutdown() to be called by pmf(9) at shutdown time,
to stop the DMA engine.
- Be consistent in WAIT/NOWAIT use in init routines
- Use BUS_DMA_COHERENT where appropriate
- Rework the interrupt routine a bit, and ACK but do not disable interrupts
here. There seems to be a race where interrupts would not be properly
reenabled after this, leading do watchdog timeouts.
