When a PA sync socket is closed, the associated hcon is also unlinked and cleaned up. If there are no other hcons marked with the HCI_CONN_PA_SYNC flag, HCI_OP_LE_PA_TERM_SYNC is sent to controller. Between the time of the command and the moment PA sync is terminated in controller, residual BIGInfo reports might continue to come. This causes a new PA sync hcon to be added, and a new socket to be notified to user space. This commit fixs this by adding a flag on a Broadcast listening socket to mark when the PA sync child has been closed. This flag is checked when BIGInfo reports are indicated in iso_connect_ind, to avoid recreating a hcon and socket if residual reports arrive before PA sync is terminated.
