Log Message:
mii(4): Wait for MIIF_DOINGAUTO to clear with MIIF_AUTOTSLEEP too.

Otherwise mii_phy_detach may return while mii_phy_auto_timeout_locked
is still in progress in another thread.

Reuse the storage for mii_nway_ch, which is unused if MIIF_AUTOTSLEEP
is set, for a new condvar in a union.  This doesn't change the kernel
ABI because sizeof(struct kcondvar) <= sizeof(struct callout) and
both have the same alignment, for an array of void *.
