Bluetooth: Fix unset of SrejActioned flag
SrejActioned is a flag that when set prevents local side to retransmit a I-frame(the data frame) already retransmitted. The local entity can retransmit again only when it receives a SREJ frame with the F-bit set. SREJ frame - Selective Reject frame - is sent when an entity wants the retransmission of a specific I-frame that was lost or corrupted. This bug can put ERTM in an unknown state once the entity can't retransmit. A frame with the Final bit set is expected when the local side sends a frame with the Poll bit set due to a local busy condition or a retransmission timer expired. (Receipt of P-bit shall always be replied by a frame with the F-bit set). pi->conn_state keeps informations about many ERTM flags including SrejActioned. Signed-off-by: Gustavo F.
