Bluetooth: ISO: Do not emit LE BIG Create Sync if previous is pending
The Bluetooth Core spec does not allow a LE BIG Create sync command to be
sent to Controller if another one is pending (Vol 4, Part E, page 2586).
In order to avoid this issue, the HCI_CONN_CREATE_BIG_SYNC was added
to mark that the LE BIG Create Sync command has been sent for a hcon.
Once the BIG Sync Established event is received, the hcon flag is
erased and the next pending hcon is handled.
