Modified Files:
        src/sys/net: if.c if.h

Log Message:
ifnet(9): Defer if_watchdog (a.k.a. if_slowtimo) to workqueue.

This is necessary to make mii_down and the *_init/stop routines that
call it to sleep waiting for MII callouts on other CPUs.

Mark the workqueue and callout MP-safe; only take the kernel lock
around the callback.

No kernel bump despite change to struct ifnet because the change is
ABI-compatible and using the callout outside net/if.c has never been
kosher.
