Bluetooth: RFCOMM: Fix CR bit in DISC frame

Browse source 
The CR bit in DISC frames should be set as a command rather than a
response.
This patch fixes the rfcomm_send_disc function to correctly use
BT_RFCOMM_CMD_CR instead of BT_RFCOMM_RESP_CR when setting the CR bit in
the address field of DISC frames.
