Fix handling IFF_UP && !IFF_RUNNING in ST_DOWN state
When netplugd has interface in ST_DOWN state and interface has IFF_UP flag
set but not IFF_RUNNING flag then it is never moved into ST_INACTIVE state.
This is because of error in FALLTHROUGH logic. Fix it by manually changing
state to ST_INACTIVE after checking for IFF_UP flag and before FALLTHROUGH
to the ST_INACTIVE switch case.
