rc: Chase 052211e08c0e and bfb202c4554a, remove ifconfig down/up

bfb202c4554a addresses the CTRL-EVENT-SCAN-FAILED. Upstream d807e289d
caused FreeBSD regression in driver_bsd.c, which this rc.d patch
worked around. As of bfb202c4554a this workaround is no longer needed.

052211e08c0e implemented this change for wpa_supplicant but not for
hostapd.
