qcacld-3.0: Flush the specific channels on ADDROAMSCANFREQUENCIES

When ADDROAMSCANFREQUENCIES is received, the specific channel
list is not flushed in the driver. This causes the static
channel list to be sent to firmware.

Flush the specific channel list when the ADDROAMSCANFREQUENCIES
command is received.
