media: cec: core: allow raw msg transmit while configuring

Browse Source 
While the CEC adapter is configuring, it is not possible to transmit a
CEC message with the CEC_MSG_FL_RAW flag set as this is blocked at the
ioctl level. Check if this flag is set, and if so, allow the message to
be transmitted. This is useful for debugging if the display has no
physical address (typically because the HPD is pulled low while in
Standby).
