leaudio: Fix handing disconnect in OOR scenario

If we call GATT Close and then force to disconnect ACL, the GATT will
send GATT CLOSED EVT before ACL is actually dropped.
Since it can take long time to drop ACL especially in the out of range
scenario where ACK might not arrive and we wait for the supervision
timeout to fire, we might end up in situation that LeAUdio code is
trying to reconnect to device which is still visible as a CONNECTED
device.

Bug: 278132584
Test: manual -- OOR scenario
