Bluetooth: Fix getting SCO socket options in deferred state
When a socket is in deferred state there does actually exist an
underlying connection even though the connection state is not yet
BT_CONNECTED. In the deferred state it should therefore be allowed to
get socket options that usually depend on a connection, such as
SCO_OPTIONS and SCO_CONNINFO.
This patch fixes the behavior of some user space code that behaves as
follows without it:
$ sudo tools/btiotest -i 00:1B:DC:xx:xx:xx -d -s
accept=2 reject=-1 discon=-1 defer=1 sec=0 update_sec=0 prio=0 voice=0x0000
Listening for SCO connections
bt_io_get(OPT_DEST): getsockopt(SCO_OPTIONS): Transport endpoint is not connected (107)
Accepting connection
Successfully connected to 60:D8:19:xx:xx:xx. handle=43, class=000000
The conditions that the patch updates the if-statements to is taken from
similar code in l2cap_sock.c which correctly handles the deferred state.
