When an interface is re-enabled after it was
disabled during CAC, it won't ever get active
since hostapd is waiting for a CAC_FINISHED
while kernel side is waiting for a
CMD_RADAR_DETECT to start a CAC.
This commit checks for a pending CAC when an
interface is enabled and if so restarts its
DFS processing.
